MGCP Fails to set ISDN Type and Plan National

Unanswered Question

I have the following issue with a MGCP Gateway running 12.4.15T7 and CM 4.1.3sr4b

Caller ID Outbound for Local calls does not work and displays on remote phone as unknown.

However, Outbound callerID is working for Long Distance calls

Contacted Provider and are forcing local calls to Plan ISND, Type National. I configured my MGCP gateway PRI settings as Calling Type National, Calling Plan ISDN and I could see this update on my debug isdq q931 when executing the outbound call. However, provider continue to see the call as unknown. I change the gateway to H323 and caller ID started working for local, LD, Intl.

For some reason the CM sends the correct calling information to the gateway but it was somehow malformed as provider continue to see the calls as unknown.


The gateway is configured as H323 but will have to be reverted to MGCP at some point.

Any help will be appreciated.

On your gateway endpoint configuration set Call Routing Information - Outbound Calls to ISDN, national.

If this won't help change on route pattern level Calling Line ID and Name presentation to allowed.

Konrad,

Thanks for your time.

Here is what I have tried


1. Under the Gateway MGCP PRI Port

Call Routing Information - Outbound Calls

Calling party IE number type unknown: National

Calling Numbering Plan: ISDN


Placed outbound call 7 Digit to Local Number. Debug ISDN q931 shows the number being sent to gateway with correct dial-plan and type, call completes, however remote user sees no callerid information on cell phone or home phone and displays as Unknown.


Provider looks at their trace and comes back telling I'm sending the calling information to them as Unknown, Unknown for local 7 digid calls.


But wait I just updated MGCP gateway, in CallManager, restart gateway after update and did no mgcp, mgcp at the gateway.


2. Same settings in MGCP gateway and I want it to keep as simple as possible. So I removed the specific route pattern for local calls configured as 9.@ and set with route filters and replaced with 9.[2-9]XXXXXX same RL poiting to same port on gateway. Check used External Phonber Mask and set Calling Line ID Presentation: Allowed

and Calling Line Name Presentation: Allowed


Placed call to same local 7 Digit Numbers, same results Callmanager sends the information to gateway, but provider sees it as Unknown, Unknown.


At this point I was like (F^*&k) it I going to switch to H323 and see if the provider is really set for National/ISDN


I Changed the gateway from MGCP to H323 updated my patterns and dial-peers. First local 7 digit call out works, of course as I have configured Plan and type at the gateway. Provider was telling the true and call routes properly with Caller ID information


I was like (damm!) works under H323, but not under MGCP. This was supposed to be simple, probably something simple i'm missing but cant come up with anything bug related under the IOS of the version of CM.

Thanks for your time
