IPitomy SIP Trunk Configuration

NOTE: All calls must go out these trunks as 11 digits, so be sure to add Prefix Digits to the trunks for the 7-Digits and 10-Digit routes.

NOTE: When naming the SIP trunk, do not use any spaces, hyphens, underscores, or special characters.

NOTE: When configuring the SIP ACL to allow IPitomy trunks to communicate to the PBX be sure to add the following: 8.38.53.40/30 so it includes 8.38.53.41 and 8.38.53.42 (for our Legacy server); also add in sip-e1.ipitomy.com and sip-w1.ipitomy.com (for our new regional redundant server).

NOTE: Moving forward, we will be building accounts only on the new regional redundant servers. Whether using IP Bound or Registration method, you'll need to add TWO SIP Providers, one for east and one for west. If using Registration method, you'll use the same Username and Password, but will need to change the HOST field in the registration string to reflect the correct server (sip-e1.ipitomy.com for East, sip-w1.ipitomy.com for West).

Migration

We have upgraded our infrastructure and have two new redundant regional servers we are using. If you have not done so already, the following link will take you to instructions on how to get this process started.

IP Bound Method

If the site that needs trunks has a static IP address, you will most likely be using the IP Bound Method to authenticate. This is going to be the easiest to set up.

NOTE:: Currently Qualify should be set to 0 to ensure the trunks work consistently. We know that monitoring the status of the trunk is an important tool for our dealers and we are working on changing this.

Please be sure to configure one SIP Provider for IPitomySIPEast, and one for IPitomySIPWest, to ensure you are fully taking advantage of our redundant infrastructure.

Registration Method

If the site that needs trunks has a dynamic IP address, you will most likely be using the Registration Method to authenticate. While this takes a little more programming, it will work just as well. You should have documentation for the trunk listing the Host, Username, Password, and Domain to be used to fill in the variables in the example screenshot below:
