Caller id..

Unanswered Question
Apr 14th, 2007

Hi,

I have configured a CCM server (version 4.2.3 ) and using MGCP gateway. We have say about 100 extensions (IP Phones), the extesion numbers range is from 2100 to 2199. Now when we place a call from any extension (outside calls to PSTN) the caller id is getting displayed is 2100 only (ofcourse with PSTN prefix).... what could be the problem why the caller id is not getting displayed as same as the extension number (along with the PSTN prefix)

Some inputs pls...

P.S. We have DID for these block of 100 numbers (2100 - 2199), and the incoming calls land on the extensions properly..

Regards

Check to make sure that the route patterns have "Use Calling Party's External Phone Number Mask" checked and there is nothing in the "Calling Party Transform Mask" field on the Route Pattern nor Route Group (within route list) nor the GW.

Check with your Telco provider to see if they can outpulse DIDs, it appears that they are masking all calls with the Billing Number.

what do your inbound calls look like on your voice gateway?

rv_viji Sun, 04/15/2007 - 06:58

Im using a MGCP gateway, so all the L2 and L3 of ISDN is being controlled on the callmanager itself, so Im unable to see any output for Show isdn active or Show isdn history.... So how else can I find the information you wanted ??

Firstly verify with your Telco that CLID is being honoured outbound.

Secondly, you could be passing too many digits across (you're currenly passing 8). Try masking this on the route list by entering 642xxx on the Calling Party transform mask. This will then force only 6 digits to be presented on the cct.

It looks like your sending the correct information to the Telco. Like most people have stated, make sure Telco is allowing the digits. Second thing you can try is to make a modification on the mgcp gateway. Under the Gateway Configuration page on the PORT in CM, change the calling party Plan Type to ISDN. Reset the gateway and see if that works. Typically for US, we use National and ISDN.
