Remote Phones Codec

We have recently moved our phone system to our data center as most of our staff work from home. We've then set up a site-to-site VPN to one of our offices on Cisco ASA5505s which works okay but every know and then we get issues with the voice quality.

Is there a way to set so the remote phones use G729 codec rather than G711? 

 

We are running on CUCM 9.1, if that makes any difference. 

 

Thank you

Hello!

You can try to put remote phones into Device Pool with  Region (System->Region Information->Region), for example Remote_reg, and configure to use g729 between other regions and inside this region.

I've tried that but if I call

I've tried that but if I call from outside, it still shows I am using G711. Would this be down to the settings on the CUBE too?

You shoukd try to configure

You shoukd try to configure codec under dial-peer, or create 'voice class codec' and apply it to dial-peer.

Saying true, full topology should be known to say exactly, what u need.

I have the following: voice

I have the following:
 

voice class codec 1

 codec preference 1 g729r8

Did you try to remove

Try to check this one:

https://supportforums.cisco.com/document/108431/dial-peer-codec-selection-cucm-region-settings-and-transcoders-sip-deployment

U need 2 scenario. Put CUBE/SIP-trunk in Reg_1 and Phones in Reg_2, and configure g729 codec between them, Xcoder will be invoked.

check if u configured Transcoder in CUCM properly (it's registered and is mentioned in MRGL's for phones and CUBE/SIP-trunk as 1st one)
