Multiple Codecs on a 323 Gateway

I have an AS5400. I am using it as a 323 gateway. I need to support 711 and 729 codecs at the same time. I have configured a voice class specifying both codecs. It works, however, there is a delay in dialing while it negotiates the codecs. This delay is very similar in length to inter-digit timeouts. Is there anyway to run multiple codecs without this delay?

Thanks,

Don

Re: Multiple Codecs on a 323 Gateway

You can try a voice class codec. You set a preference for the which codec to try first and then next. I have never felt a delay in dialing out

voice-class codec 1

codec preference 1 g729r8

codec preference 2 g711ulaw

dial-peer voice 200 voip

destination-pattern 2

ip precedence 5

voice-class codec 1

session target dns:cm1.cisco.com
