Transcoding

Answered Question

I have a customer which has 2 sites. Site A has all the CCM, Unity Connection & IPCCX servers with no users nor IP Phones, while Site B has all the users, phones and the two 3825 Voice Gateways. Site A & Site B are linked by WAN only.

I have setup 2 regions for each of Site A & B, specifing 'codec to other region' will be G729 while 'codec within region is G.711'.

Now, both of my Voice Gateways on the site with all the IP Phones, do i still need to apply 'transcoding' on the Voice Gateways to do G729 across WAN? Or will G729 work automatically between the two sites without the transcoding?

Thanks,

Hunt

I have this problem too.

Most of the queuing or IVR functions of IPCC require a G.711 codec. You pick the prompt format when you install IPCC, which did you select? The IPCC SRND gives some good guidance on this.

Normmaly Cisco GWs support G729 which IP Phones also support...hence no Xcoding will be needed

Hi,

While can, always avoid to do transcoding, you can reduce the MOS in a significant amount.
