Is there a way to enable transcoding using the CCA.

Unanswered Question
May 11th, 2012

                   Hi.I have little knowledge of using the CLI when It comes to Voice configurations so for now I'm using only the CCA.

I've setup a UC540W and everything Is working fine.Their Is a problem with the bandwidth however so I've been forced to used g729 on the SIP trunk.

I cannot access AA and Voice mail and from what I've understood , they require G.711 Ulaw.Is there a way I can enable transcoding through the CCA?

I have this problem too.

Hi,

When you select the SIP trunk protocol g729 it should enable the transcoding if it is not created you can try to delete and recreate the SIP trunk. Also you can try with enabling the conference with g729.

HTH,

The conference will not help. If you enable conference the CCA will create profile dspfarm profile profile-identifier conference.

As Alexander told you enable SIP trunk to support g729 and see do you have transcoding profile. If you do not have it you could do it manual on CLI

Hi.I've attached the current startup config.I'm still having trouble with the auto attendant and voice mail.I receive an unknown number when trying to access them.I've tried enabling g711 ulaw as main and alternate codec but I still can't access them.

Thank you.
