I am having an issue with no audio when I call from a Cisco IP SCCP Phone registered to Call Manager to an analog phone registered to a SCCP VG 224. Howerver, calling the other way works fine. So, it seems to be an issue with the VG 224 receiving a SCCP call as we have tested a lot of other scenarios and they work fine. Anyone have any ideas?
OK, we have another piece of info for this. If we wait for the analog phone to ring twice and then pick up, it works. So it seems to be something with the VG not being able to setup completely for the RTP to function correctly. We are running 12.4(15)T1. Any ideas?
