Hi Michael, Thank you for your reply.
For the Cisco phone the default is g711ulaw codec. AFAIK, polycom use g722 as preferred codec. In Gateway > Voice Codec, I selected g711ulaw and g723.1. g711ulaw is on top of g723.1. For the Phones > Polycom, I selected g711ulaw as preferred over g722. For the Phones > Cisco, I selected g711 ulaw as preferred over g723.1 I applied/send the profile to the phones and gateway, restart the sipxecs services, phones and my Audiocodes as well. But the problem remained. Whenever you make a call from Polycom, the IVR will prompt automatically and says "The extension is not available". Any thoughts on how to fix this? Thanks in advance.
