I'd like to set up VG224 to support analog phones, modems, and fax machines with extensions on DID blocks. I've followed Cisco's SCCP Controlled Analog (FXS) Ports doc, and have successfully configured a voice port for an analog phone. However, the same config doesn't work when attaching fax machine. Fax machines generally transmit/receive faxes to/from external parties, not over IP WAN.
Recent posts recommend MGCP over SCCP but suggested configs may not work in my environment. I have a PRI terminating on a Catalyst WS-X6608-T1 module. CallManager 4.1(3)SR4d in single cluster, VG224 running 12.4(2)T5, configured in CCM as SCCP gateway with all 24 endpoints as analog phones.
At a high level, Cisco IOS Release 12.3(1) - Load 47 on the Cisco 6608 and Load 41 on the Cisco 6624 - and Release 1.2.1 on the VG248 do support interoperability of Cisco fax relay, modem pass-through, and voice features. Prior to Cisco IOS Release 12.2(11)T1, only voice and Cisco fax relay were supported between Cisco IOS and non-IOS voice platforms because incompatibility of the pass-through Named Service Event (NSE) scheme prevented modem pass-through from interoperating
