H323 Inbound Dial Peer

[billsayegh]

Hi

I was reading Cisco book on dial peers and wanted to understand the logic of inbound dial peers.

1. Why would you match on inbound dial peer, would it be for say a call centre to match on who is dialing. What would you do on the inbound dial peer when you match on answer-address.

2. Match the calling number to the destination pattern that is configured on the dial peers. What does this mean does it mean the inbound dial peer is matched on a destination pattern, wouldn't you need to configure the next hope peer.

3. Match the default dial peer 0 is this in the config that you can enter the dial peer 0 and configure it.

Any help would be appreciated.

Thanks

Bill

Bill,

Here is a good document.

1. There is always an inbound peer, and often you want some sort of special treatment, so you don't want to use the default peer. I have used answer address on a POTS peer to ensure that incoming calls to specific FXO ports (with station ID number on port) used an autoattendant TCL script assigned via the peer.

2. This just ensures that the same peers are used for incoming and outgoing calls. A call goes out via VOIP peer 101 to destination 1234. When a call comes into the router from 1234 (calling number now) it matches incoming peer VOIP 101, and gets the same treatment as the outgoing call.

3. Peer 0 cannot be modified.

Strange things happen when your calls are not using the peers you think they are. show call active voice brief is a very useful troubleshooting command.
