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.
voice service voip
fax protocol pass-through g711ulaw
dial-peer voice 107 voip
description "Voip out to SIP Provider"
translation-profile outgoing SIP-Outbound
voice-class codec 1
session protocol sipv2
session target dns:sip.xxxx.com
dial-peer voice 109 pots
description "Voice in from PSTN"
incoming called-number .
Thanks for your help.
