Configuring Dial Peer Hunting

Configuring Voice over IP for Cisco MC3810 Series Concentrators 11

Foradditional VoIP dial-peer conﬁguration options, refer to the “Voice-Related Commands” section

of the Cisco IOS 12.0 Voice, Video, and Home Applications Command Reference. For examples of

how to conﬁgure dial peers, refer to the section, “Voice over IP Conﬁguration Examples.”

Validation Tips

You can check the validity of your dial-peer conﬁguration by performing the following tasks:

• If you have relatively few dial peers conﬁgured, you can use the show dial-peervoice command

to verify that the data conﬁgured is correct. Use this command to display a speciﬁc dial peer or

to display all conﬁgured dial peers.

• Use the show dialplan number command to show the dial peer to which a particular number

(destination pattern) resolves.

Troubleshooting Tips

If you are having trouble connecting a call and you suspect the problem is associated with dial-peer

conﬁguration, you can try to resolve the problem by performing the following tasks:

• Ping the associated IP address to conﬁrm connectivity. If you cannot successfully ping your

destination, refer to the Cisco IOS 12.0 Network Protocols Conﬁguration Guide, Part 1.

• Use the show dial-peer voice command to verify that the operational status of the dial peer is up.

• Use the show dialplan number command on the local and remote routers to verify that the data

is conﬁgured correctly on both.

• If you have conﬁgured number expansion, use the show num-exp command to check that the

partial number on the local router maps to the correct full E.164 telephone numberon the remote

router.

• If you have conﬁgured a codec value, there can be a problem if both VoIP dial peers on either

side of the connection haveincompatible codec values.Make sure that both VoIP peers havebeen

conﬁgured with the same codec value.

• Use the debug vpm spi command to verify the output string the router dials is correct.

• Use the debug cch323 rtp command to check RTP packet transport.

• Use the debug cch323 h225 command to check the call setup.

Conﬁguring Dial Peer Hunting

After you have conﬁgured dial peers, you can conﬁgure how the router or concentrator performs

dial-peer hunting functions. To conﬁgure dial-peer hunting behavior, perform the following steps

beginning in global conﬁguration mode.

router(config-dialpeer)# dtmf-relay [cisco-rtp]

[h245-signal] [h245-alphanumeric]

(Optional) Specify how an H.323 gateway relays DTMF

tones through an IP network. Options allow the gateway to

forward tones “out-of-band”, or separate from the voice

stream.

Note This command is only supported if your Cisco MC3810

has version 549 or newer DSPs.
