Call forward calling number

Unanswered Question

Here is my scenario:


Phone A is a mobile GSM phone

Phone B is a Cisco IPphone

Phone C is a mobile GSM phone


Test 1:


I setup a CFA on phone B to phone C. Phone A calls Phone B, then this call is forwarded to C and phone A number is shown on C. Here everything works as expected.


Test 2: Phone B is still on CFA to phone C. Phone A calls Phone B with a private call (hidden calling number), this call is forwarded to C but the caller id shown is the main number of the DID range and not a restricted (or private) display.


In this case (test 2), i would prefer that phone C receive a private call (restricted caller id) and not shows the main number, that only when the forward concerns a private call from phone A.



Thanks in advance for any help


We run CUCM 7 and MGCP gateway.

Any outbound call on a gateway can send directory number information. Calling Party Selection field determines which directory number is sent.

Originator--Send the directory number of the calling device.

First Redirect Number--Send the directory number of the redirecting device.

Last Redirect Number--Send the directory number of the last device to redirect the call.


Choose whether the Cisco CallManager transmits or blocks the calling line ID.

Choose Calling Party Presentation Allowed if you want the Cisco CallManager to send calling line ID.

Choose Restricted if you do not want the Cisco CallManager to send calling line ID.

dear anatsira,


I have a problem in your Test 1, can you help me? what parameters need been set in CCM or GW?


My Test:


A is a external telephone, such as GSM

B is a Cisco ip Phone

C is external telephone, such as GSM

we settings "no answer forward" to C on B.

when A call B,B forward the call to C. B's number is displaied on C. Now I want to show A's number on C.

My CM version is 5.1.2.3000 and it is base H.323. I can see A's number base on mgcp.


I have set originator, and enabled outbound IE, but my gw reject this call when it see the A's number is not in DID range.

Hi,


Your settings seem good (setting with originator), are you sure your gw rejects this call with originator setting? i should say it's your telco...


Do you have the debug isdn q931 traces?

Thanks a lot, anatsira

Below is my debug result yestoday.

It seem that service provider do not support isdn IE. and I have try others signal, such as qsig,5ess,4ess, and it still do not work.


Because customer told me that it works well when we use MGCP protocol, so the SP may allow calls when A's calling number is a GSM number which not in range of DID.

i see this in your traces:Redirecting Number i = 0x00008F, '5028206'



In your H323 config, you certainly checked the box which name should be "Redirecting Diversion Header Delivery - Outbound"


If yes, uncheck this box et do another test.


If it doesn't still work. Try a direct call from B to C with "013911734336" as the calling number of B (external phone mask)



If it doesn't still work, your Telco doesn't probably support calling number which isn't in your DID range.

Thanks for your reply.


I have confirmed that Telco doesn't support calling number which isn't in my DID range.


But customer sure that it is work well before Gateway change protocol MGCP to H.323.


And I will do a test with uncheck box "Redirecting Number IE Delivery - Outbound" next week.


thanks a lot.
