Providers

Providers provide telephone network connectivity, (a.k.a PSTN connectivity).  Examples of providers:  an analog telephone line, or a SIP Provider or a T-1 PRI.  VoIP providers and other telecommunication resources. This section of the system is where these provider resources are configured. The PBX system is equipped to handle two types of providers:  Hardware and SIP providers.  

Hardware Providers

Hardware providers or trunks are associated with telephone lines that connect to the PSTN. These lines process inbound and outbound communication traffic that flows over communication channels. For example, a T1 can be a trunk resource that has multiple lines and multiple Direct Inward Dialed (DID) numbers. These individual numbers can be routed to different destinations within the system.

Connection Types

The IP PBX is equipped to support an assortment of hardware cards as discussed earlier. Depending on which card you have, the PBX can integrate with analog lines, T1, or PRI.

Provisioning a New Hardware Trunk Group

Provisioning a hardware trunk defines how the system works with the provider equipment, tells the system what phone numbers are associated with the trunk, and establishes rules for the system to follow when processing incoming and outgoing calls through this physical network connection.

The following table describes the fields and functions available on the Hardware Trunks Provider Configuration page.

Section	Description
Configuration Section
Slot	Defines which physical PCI slot the card is connected to.
Channels	This indicates whether the card has channels configured. Using the mouse to hover over this field will provide you with the number of channels at are set for this card.
Model	This is the model or type of card.
	This button changes the card set in the database for the adjacent slot. The change is immediate and will delete trunks associated with another card in the same slot. NOTE: You must delete channels from outbound routes in order to delete them. The Set action will not work until all trunk groups are removed from outbound routes.
	Selecting this button will take you to the Channel Group Parameters Card Configuration page, where you can create a channel group.
Channel Groups Section
Name	The name associated with this channel group.
Channels	The number of channels that have been assigned.
Card	The card number associated with the channel group.
Action	- Clicking on the pencil icon allows you edit the settings for the selected channel group. - Clicking on the “X” icon allows you to delete/remove the selected channel group. NOTE: You must delete channels from outbound routes in order to delete them.
T-1 Span Configuration
Span	Should automatically set to the appropriate span in regards to the cards that are installed in the PBX.
Timing	Set per your providers instructions, “0” (zero) would be the PBX provides timing, “1” would be the timing is provided by the Provider.
LBO	Line Build Out, set per your providers instructions.
Framing	Set per your provider’s instructions.
Coding	Set per your provider’s instructions.
PRI	Check if the trunk is a PRI, leave blank if the trunk is a standard T-1.
T-1 PRI Configuration
Span	Should automatically set to the appropriate span in regards to the cards that are installed in the PBX.
Switch Type	Defines what type of equipment the PBX is communicating with. Set per your provider’s instructions.
Reset Interval	Set per your provider’s instructions.
Dialplan	Set per your provider’s instructions.
Indication	Set per your provider’s instructions.

Hardware Functions
Restart USB Devices & PBX Services	This button will restart USB devices and PBX Services.

Table 12Hardware Trunk Provider Settings and Descriptions

When configuring Mutliple PRI Cards or one card with Multiple ports, its important to know the following.

• D Channel is Always 24
• Multiple Port cards increment the start and end channel. So you'd make a channel group for 1-23, then a channel group for 25-47, and so on.
• Channel numbering starts over when you have a second card. So you'd start over with a channel group for 1-23 for the second card.
• Timing increments as you go along on the same card. Span 1 would be timing 1, span 2 would be timing 2, etc.

Configuring Hardware Trunks

STEPS:

1. Navigate to Providers->Hardware Trunks. The Hardware Trunk (Providers) page appears. The hardware trunks and their values that have already been provisioned will be displayed.
2. The system will allow configuring of up to 2 cards that interface with analog or T-1 devices. Select the card models installed in your IP PBX individually and click Set button for each card in order to tell the system which cards you have.
3. Once you have set the card, click the Add Lines button to the right of the corresponding card to define line/channel/trunk groups associated with that card. The Edit Hardware Provider page appears.

   

4. Edit the necessary parameters. Required fields are: Group Name, Signalling Type, Start Channel, and End Channel. The rest of the fields can be configured as needed, or left at their defaults. (refer to the table below for descriptions and recommended settings)
5. Click on the button.
6. Click the Apply Changes link located on the right hand corner of the page to commit the changes to the database.
7. Once the changes are applied, navigate to the Hardware Providers page and click the Restart USB and PBX Services button.

The following table describes the fields and parameters available on the Add/Edit Hardware Provider Configuration page:

Section/Field	Description
Channel Group Parameters Card 1
Group Name	This is the name for the groups of channels you want to create. This Group Name will be associated with the line/channel group.
Signaling Type	This is the type of signaling used for these channels/lines. Recommendation and default settings are listed below: Analog lines should be set to fxs_ks. T-1 lines should be set to fxs_ls or em_w T-1 PRI lines should be set to pri_cpe.
Generate Ringing on Outbound Calls?	This should only be checked if the telephone company is not providing ringing. Default this is disabled.
Answer Incoming?	This indicates whether the system should answer incoming calls on these lines/channels. The default value is Yes.
Start & End Channel	Used to define the Start and End channel for this group on the associated card. If you would like a 1 channel group set the start and end channel to the same value (i.e. Start=1 and End=1). IMPORTANT: If you wish to address analog lines individually you must build multiple single channel groups. T1 and PRI can be grouped with multiple channels and routed via DID.
FAX Detect	Enabling this allows automatic fax detection so you can set a Fax Destination in a menu.
Allow Caller to transfer outbound call?	This indicates whether the system will allow user to transfer a call they origninated that has been connected to the PSTN. Default this is disabled.
Disable Pre Answer Ringing?	When checked, ringing will not be sent prior to the PBX answering the call.
Answer After	If the system is configured to answer incoming calls, this defines how many seconds to wait before answering the call. At times this field needs to be tweaked to ensure consistent CID. Default this is set to 0.
Dial Prefix	Digits defined here will be dialed out the trunk ahead of the digits dialed by the user. This would be required if your provider needs a 9 or some other digit to dial outbound. Analog trunks might need a one second pause which is denoted by a lowercase w. Default this is blank.
Allow Call Recording?	This setting toggles the ability to record calls on this trunk. Default this is disabled.
Ext CID Override?	This setting allows the users to set an alternate caller ID under their extension that will override the outgoing caller ID. If this is enabled, then this allows extension caller id override capabilities. Default this is disabled. IMPORTANT: Contact your provider to determine whether CID override is allowed on your specific trunk
Restrict CID Override?	This setting is used to limit an extension’s ability to override Caller ID (CID). If enabled, this allows extension CID Override only for the phone numbers defined for this provider. Default this is disabled.
Use Caller ID	This setting indicates whether the system should attempt to detect caller id on the lines/channels in this group. Default this is set to Yes.
Echo Cancellation	This allows you to configure the Echo Cancel parameter. By default this is set to Yes (128) which will work in most scenarios. Adjustments can be made as needed.
RX Gain	This allows you to set or adjust the gain on sound received from these lines/channels. Typically these settings don’t need to be changed from default settings, unless there are issues relating to the volume on the calls. (This setting is in decibels so 3.0 = 100% increases in volume). Default this is set to 0.0.
TX Gain	This allows you to set or adjust the gain on sound transmitted to these lines/channels. Typically these settings don’t need to be changed from default settings, unless there are issues with the volume on the calls. (This setting is in decibles so 3.0 = 100% increases in volume). Default this is set to 0.0.
Echo Cancel Algorithm	Default is MG2. If using a PRI and experiencing issue with echo, change to OSLEC. After applying changes, services need to be restarted for this change to take effect.
Inbound Caller ID	This is the name of the Caller ID of the inbound calls on this trunk. If set to the system default “asreceived', the calls will capture the Caller ID information sent over the incoming lines. Otherwise you can override the name and number that appears to those receiving calls on the corresponding channels. IMPORTANT: If you need to change this parameter, we recommend that you contact IPitomy’s Technical Support Group at (941) 306-2200 for the proper syntax or additional information.
Echo Cancellation Bridged	This allows you to enable or disable the Echo Cancellation Bridge parameter on calls routed internally across the network. Set this parameter to”YES” (enable) if you want echo cancellation on calls that are bridged from one port to another on the network. Default this is set to No.
Busy Detect	By default, this is set to YES and8. This allows you to enable/disable and set the number of busy signals the system will detect before disconnecting from the call (hanging up). Set the parameter to “YES” if you want the PBX to hang up after it detects a busy signal. The number field is the number of busy tones the system must detect before it disconnects from the call (hangs up).
Outbound Caller ID Name	Any values entered here will display as the Outbound CID Name when making calls out this trunk. If this is left blank, the name displayed on outbound calls will match what is registered with the provider. Blank by default. IMPORTANT: Contact your provider to determine whether CID override is allowed on your specific trunk
Outbound Caller ID Number	Any numbers entered here will display as the Outbound CID number when making calls out this trunk. If this is left blank, the number displayed on outbound calls will match what is registered with the provider. Blank by default. IMPORTANT: Contact your provider to determine whether CID override is allowed on your specific trunk
Echo Training	This parameter is used to adjust the time spent training the echo cancellation algorithm before a call is picked up. The length of time is set in milliseconds (ms), and is set to 800 by default.
Route Calls to	This is the default destination for the trunk. A destination is where calls from this provider will be routed to, unless a specific Direct Inward Dial (DID) is indicated. A typical destination is defined as a Menu, Extension, Schedule, Voicemail, or a Ring Group. This can also be set under the Incoming Routing page.
Relax DTMF (Detection)	This allows you to turn On/Off the Relax DTMF detection. Enabling this setting allows the line/channels to be more permissive of tone lengths and result in over detecting. By default this is set to No. IMPORTANT: We recommend that this parameter is set to NO unless you are having issues. Please contact IPitomy’s Technical Support Group for assistance or more information.
DTMF Tone Duration	This allows you to set the DTMF tone duration in milliseconds (ms) for generated tones generated by calls bridged to SIP devices. Default value of 300.
Use Inbound CoS	This allows you to enable/disable inbound routing and provides the dial plan that corresponds to the outbound routes in this Class of Service (CoS). This is Off by default. IMPORTANT: Use this only if you intend to provide PSTN connectivity to 3rd party equipment. Please contact IPitomy’s Technical Support Group for assistance or more information.
Phone Numbers	On a T1 or PRI, this is where you would configure any DID information. Only numbers or a + should be entered for a DID. Once configured, you can define a different inbound destination for each number, allowing you to route calls to separate places. Contact your provider to find out if they are sending 4, 7, or 10 digits inbound for the DID.
Dial Out Order	Default is Ascending (start at 1 for outbound calls, counting up till a free channel is found). Swap to Descending to get calls to start outbound at the highest channel. This is recommended if you are having issues with call collision.

Add Phone Numbers to Hardware Provider

Once all the destinations are created, they will appear in a drop-down list and can be selected for updating.

STEPS:

Provisioning a SIP Provider

SIP Providers are VoIP service provider accounts or other SIP-based devices that provide PSTN connectivity. SIP provider accounts can have multiple phone numbers or Direct Inward Dialing numbers (DIDs). The individual numbers can be routed to different destinations within the system as DIDs. 

IPitomy SIP Wizard

Click Add IPitomy to use the Wizard to add IPitomy SIP Trunks. This will create a SIP Provider for our East and West servers. Once done, you'll need to add in your DIDs, Outbound CID, and set the Call Limit to however many trunks you have; everything else is done for you.

Your Activation Letter will tell you if you are using IP Bound trunks or Authentication.

• If IP Bound you won't have a username/password
  • Choose Static and click Submit
• If Authenticated, you will be given a username, password, and domain
  • Choose Dynamic and enter the information given in your activation letter to the correct fields, then click Submit

Manually Programming SIP Provider

IMPORTANT: SIP Providers settings vary widely. To simplify the provisioning process, we recommend that you ask the provider for a sample Asterisk configuration. Please contact IPitomy’s Technical Support Group for assistance.
