I had been under the impression (after actual tests) that the GSM codec supplied with Asterisk was not compatible with the GSM codec supported by the Cisco VoIP equipment (PRI and DS3 gateways.) However, I hear recent news that this is no longer the case. Can someone with a "big" Cisco media gateway (58xx or similar) please test and let the community know if this works with recent IOS images? I will attempt to test with a "small" media gateway in the near future, but my schedule is pretty much booked solid for the next week. JT

The problem of no support for MGCP+GSM is from Cisco. I have a Cisco 5300 with 12.2(something) which is controlled by BTS (no PRI but SS7) but I was playing with the config and it seems that the 5300 does support GSM but only with SIP. -- Juanjo sin .sig
