VoIP Dial Peer Destination Pattern

Hi, I want to ask that I have two site which have telephony services.

At the Extension 1, when I press number 1000, it shows the message "To 1" and "Busy".

At the Extension 1000, when I press number 1, it shows "Unknown number".

So how can I configure the dial-peers or destination-pattern that can make phone call successfully between these two phones?

The part of the configuration of Extension 1000 Side

dial-peer voice 1 voip
destination-pattern [1-9]$
session target ipv4:10.0.0.1

The part of the configuration of Extension 1 Side

dial-peer voice 1 voip
destination-pattern 1[0-9][0-9][0-9]$
session target ipv4:10.0.0.2

Hi Alan,

Right now you have an overlapping dial plan (extension 1 has the same first leading digit as extension 1000).

In the first section of debug (where phone 1 tries to call 1000) we can see the following:

*Mar 20 04:18:17.651: //-1/xxxxxxxxxxxx/DPM/dpAssociateIncomingPeerCore:
Match Rule=DP_MATCH_ANSWER; Calling Number=1

*Mar 20 04:18:18.075: //-1/9B4D661082B8/DPM/dpMatchPeersCore:
Match Rule=DP_MATCH_DEST; Called Number=1

List of Matched Outgoing Dial-peer(s):
1: Dial-peer Tag=20001


When you tried to dial 1000 from the phone with the extension of 1, the CME matched "1" immediately and tried to route it to the DN on the phone with extension 1 (phone 1 is calling itself). Since phone 1 only has a single line DN, the call will ring busy.

To make it much easier I would suggest configuring the different sites with non-overlapping extensions, for example change phone 1 to extension 2000. That way, you will have no overlap between the sites and will be able to dial properly without being interrupted.

If you are using digit-by-digit dialing and not enbloc dialing, there is no really clean method for the topology you have created. There are ways you could "make it work" using translations or DNs with call forward all set, but the best design would be to assign non-overlapping extensions to your sites.

I am not sure if packet tracer supports it, but if you do an enbloc dial from phone 1 to phone 1000 it should work based on the dial-peers you have configured.

To perform an enbloc dial from phone 1, dial the number 1000 while the phone is on hook, and then press the dial button. Since the digits are sent all at once to the CME, it should not match dial-peer 20001.

Let us know if this helps.

Add "incoming called-number ." under the dial peers. If the issue persists then share the complete config.

I add the incoming called-number . under the dial peers, but the problem still exist.

This is the configuration related to VoIP

I also enable debug voip dialpeer all and try to call extension 1000 from extension 1, it always hit to DIal-peer 20001 

This is the debug message from Extension 1 Site's Router.

And on the Extension 1000, I try to call extension 1 and it works, but I call extension 1002 it still transfer it to extension 1, the message on the IP phone shows "To 1".

Hi Alan,

Right now you have an overlapping dial plan (extension 1 has the same first leading digit as extension 1000).

In the first section of debug (where phone 1 tries to call 1000) we can see the following:

*Mar 20 04:18:17.651: //-1/xxxxxxxxxxxx/DPM/dpAssociateIncomingPeerCore:
Match Rule=DP_MATCH_ANSWER; Calling Number=1

*Mar 20 04:18:18.075: //-1/9B4D661082B8/DPM/dpMatchPeersCore:
Match Rule=DP_MATCH_DEST; Called Number=1

List of Matched Outgoing Dial-peer(s):
1: Dial-peer Tag=20001


When you tried to dial 1000 from the phone with the extension of 1, the CME matched "1" immediately and tried to route it to the DN on the phone with extension 1 (phone 1 is calling itself). Since phone 1 only has a single line DN, the call will ring busy.

To make it much easier I would suggest configuring the different sites with non-overlapping extensions, for example change phone 1 to extension 2000. That way, you will have no overlap between the sites and will be able to dial properly without being interrupted.

Hi, Jonathan.

Thank you for your explanation!

But are there any ways to do it without changing extension?  For example, configure the voice translation-rule or something else.

If you are using digit-by-digit dialing and not enbloc dialing, there is no really clean method for the topology you have created. There are ways you could "make it work" using translations or DNs with call forward all set, but the best design would be to assign non-overlapping extensions to your sites.

I am not sure if packet tracer supports it, but if you do an enbloc dial from phone 1 to phone 1000 it should work based on the dial-peers you have configured.

To perform an enbloc dial from phone 1, dial the number 1000 while the phone is on hook, and then press the dial button. Since the digits are sent all at once to the CME, it should not match dial-peer 20001.

Let us know if this helps.
