[cisco-voip] SRST automatically set to G.729 CODEC instead of G.711

[Ryan Ratliff]

You don't want to be doing g.729 MOH anyway as it sounds very, very bad.
If you don't have a transcoder then you can look into playing  
multicast MOH from the flash of the SRST router.

Jonathan,
Thank you for the reply.
I have confirmed that all the phones and SRST gateway are in correct
device pool and within this region codec is set to G.711. When changed
dial peer codec to g711ulaw it works fine but MOH for PSTN doesn't play
but local extension. This is because
Between Callmanager  and SRST ---> G.729
Between SRST and PSTN ---> G.711

So, as I have SRST set to G.711 it cannot send MOH which come as G.729

We are going to try voice class codec tomorrow and see whether it work.

For example.,

voice class codec 1
  codec preference 1 g711alaw
  codec preference 2 g711ulaw
  codec preference 3 g729r8

dial-peer voice xxx
  voice-class codec 1

Regards,
MP

The default codec for a voip dial peer is G.729...

add

codec g711ulaw

to your voip dial peers
