I have a router configured with 3 PVDM-12 DSPs. They are configured for transcoding and conferencing.
show sccp returns the following:
SCCP Admin State: UP
Gateway IP Address: 10.1.10.2
Switchover Method: IMMEDIATE, Switchback Method: GUARD_TIMER
Switchback Guard Timer: 1200 sec, IP Precedence: 5
Max Supported MTP sessions: 0
User Masked Codec list: None
Transcoding Oper State: ACTIVE - Cause Code: NONE
Active Call Manager: 172.16.2.1, Port Number: 2000
TCP Link Status: CONNECTED
Conferencing Oper State: ACTIVE - Cause Code: NONE
Active Call Manager: 172.16.2.1, Port Number: 2000
TCP Link Status: CONNECTED
Call Manager: 172.16.2.1, Port Number: 2000
Priority: 1, Version: 3.1 or Higher
I have 3 Media resource groups in a single Media resource group list.
1. Xcode resources from above router
2. Software conf resources from Call Manager
3. Conf resources from above router.
Hardware conferening works fine when I move the hardware CFB above the CCM Software CFB in the resource list.
However, when I give Software conferencing higher priority, it does not work, when I try to connect from a region that uses G729. It appears that my transcoding resources are not working properly for some reason, but they are registered with Call Manager and the conferencing resources on the same router function properly. As you can see from the show SCCP all looks good. Transoding and Conferencing are ACTIVE on the router.
If I try to dial a meet me number when Software conferencing has the priority in the MRGL I get a busy signal. With Hardware conferencing as the priority, it works fine. Can't figure out for the life of me why the transcoders don't work.
thanks in advance
