SIP Inbound DP Question

[balitewiczp]

I am moving from a PRI connection to SIP/SIP, using a cube.  In the PRI world, for inbound calls, I had a translation pattern on the imcoming pots dial peer, and simply used the "incoming called number ." to match all incoming calls.

when I configured the respective inbound DP's (one inbound from ISP, the other Inbound from  Phones) SIP voip dial peers, I have

dial-peer voice 100 voip
 description Inbound from SIP
 translation-profile incoming 10_to_4_IN
 session protocol sipv2
 incoming called-number .
 dtmf-relay rtp-nte
!
dial-peer voice 2005 voip
 description Outbound from CUCM
 voice-class codec 2
 no voice-class sip early-offer forced
 session protocol sipv2
 incoming called-number .
 dtmf-relay rtp-nte sip-kpml sip-notify

How do I know or guarantee that inbound calls from the ISP will use the correct DP if both have "incoming called number . "?   Also, is there an easier way to see DP matching other than debug voice dialpeer?

Thanks

You can use different incoming called number rather than using . This way you have the flexibility to make digit manipulations based on the different voip legs..

eg your inbound dial-peer from cucm can look like this..

dial-peer voice 2005 voip

incoming called number XX (where XX is the number range dialled from your ip phones..eg 8T or 9T)

Then your inbound dial-peer from ITSP can be something like this

dial-peer voice 100 voip

incoming called number YYYYY (where YYYYY will be your DDI range)

On your second question, I have to say I have debug voip dialpeer, so I use debug voip ccapi inout. This will show you which dial-peer is matched for both inbound and outbound call legs

ok, thanks for the quick reply.  I didnt realize I could use T in incoming called number.

Would another approach be leaving incoming called number .  and then putting my translatiion patterns as outgoing on the outgoing dial peers
