conference no audio witch HW CFB

[Agustin Varela]

Hi all guys, i have an issue an need some help and orientation, thnk for now.

Site 1

CUCM sub

phone A

phone B

Site 2

phone C

Router 3925 --> v 15.2(2)T --> PVDM3-256

SItuation:

the idea is when the phone c want to start a conference it ask resources from the 3925 router and don´t from cucm cross the wan.

the call is stablishd between phone a and phone c with no problemas, good quality, right audio, etc. Phone C begin to start a conference, press conf, call phone b, and then press conf again for stablish the conference..... the conference is stablished but with no audio at all, in any direction. but

when one phone leave the conference the audio come back normaly between point to point call.

when the conference is hosted by the gateway, the audio flow between the phones and gateway. i dont know what could be.

thank for you help, and i attach show run and show ver

regards

Issue the command "show sccp" you should see the Conferencing Oper State: ACTIVE

It should also show the active call manager that the conference profile is registered with and the TCP link status should show CONNECTED along with all the supported codecs you have configured.

On the call manager side did you configure the conference bridge as Cisco IOS Conference Bridge or Enhanced Cisco IOS Conference Bridge when creating this? If you used the hardware option I dont think this will work in this scenario.

And your transcoder is in shutdown.

On another quick note, everyone here is trustworthy I know - but you should really take out your passwords, usernames and ip addresses when posting configs. Password 7 is very easy to crack.

hi tracy, you righ about the passwords, sorry my mistake.

about configuration:

i attach sh sccp, everythink looks good.

in the cucm i registered cfb like Enhanced Cisco IOS Conference Bridge.

and, its necesary that transcoder is UP ?

i shutdown only for test cfb, but when the transcoder is UP nothing change.

i registered the transcoder in CUCM like Enhanced Cisco IOS Conference Bridge
