Dial peer 0 for inbound VoIP peers has the following configuration:

 any codec

 ip precedence 0

 vad enabled

 no rsvp support

 fax-rate service

Dial peer 0 for inbound POTS peers has the following configuration:

 no ivr application

You cannot change the default configuration for dial peer 0. Default dial peer 0 fails to

negotiate nondefault capabilities or services. When the default dial peer is matched on a VoIP

call, the call leg that is set up in the inbound direction uses any supported codec for voice

compression, based on the requested codec capability coming from the source router. When a

default dial peer is matched, the voice path in one direction may have different parameters than

the voice in the return direction. This may cause one side of the connection to report good-

quality voice while the other side reports poor-quality voice; for example, the outbound dial

peer has VAD disabled, but the inbound call leg is matched against the default dial peer, which

has VAD enabled. In this example, VAD is on in one direction and off in the return direction.

When the default dial peer is matched on an inbound POTS call leg, there is no default IVR

application with the port. As a result, the user gets a dial tone and proceeds with dialed digits.
