We often get asked how to configure the AT-610 to connect to an asterisk server using IAX protocol.

It is important to note that the AT-610 has two seperate firmware images, one for SIP and one for IAX. By default the AT610 ships with SIP Protocol firmware and therefore if you need IAX functionality, please download the IAX firmware from Atcom's website and update from the GUI.

One important note is that if you have previously configured the phone for SIP, then you need to clear down the configuration in the GUI before performing an upgrade to IAX.
