You will need to ensure that when the incoming call arrives at your AS5300, that it matches an incoming dial-peer that has the G723r63 codec specified. If the incoming call matches the default codec, then the call will fail.

If you have multiple calls arriving at the gateway using a variety of codecs, then you will have to configure a voice class that contains a list of codecs that you will accept, and then apply the voice class to the incoming dial-peer.

The following links will help give you an understanding of Dial-peer matching in the router.

The following link talks about the G723 codec differences.

The following link gives an example of configuring the voice class.

Hi

Try this, it should work.

NOTE: the 4444 is a prefix.
