Router Compatibility List

Mikrotik

This router has an ALG that can be disabled with the following command

• /ip firewall service-port disable sip

The info was found at the following two links Mikrotik Wiki Mikrotik Forum

Fortigate

I found this online about solving issues with Fortigate routers and NO AUDIO with remote SIP:

In the command line of the fortigate type the following:

• config system settings
• set sip-helper disable
• set sip-nat-trace disable

Reboot the device

In the command line type the following:

• config system session-helper
• show

(now look for SIP, mostly it will be "12")

• delete 12

Don't use any protection profiles on the firewall of the sip rules.
