Hi, We have recently installed a Cisco 2811 at our customer site where we are providing SIP services. This GW connects to the customer's Nortel PBX via an E1 and also to PSTN via an E1, it also connects to the SIP provider via IP. We want to route all the calls including fax to the SIP provider.
Though the VOIP calls are working fine but the incoming and outgoing fax don't work, below is the config for fax passthrough that we want to use. I have also attached the debug output of the fax call but I am struggling to interpret it.
Hi, The PBX is set to user or to get it's clocking from the Cisco GW as per the Nortel engineer. I was going to change the fax protocol to T38 but the SIP provider doesn't support T38. So I am really not sure what to do.
