call forwarding issue with the calling number ID

I have CUCM 11.5 with sip trunk to  CUBE as CUCM>CUBE>SIP service provider, I have two situations at call forwarding:

1- I configure call forwarding for extension 7799 to forward calls to cell phone, so when I call from ext 7766 to ext 7799 I received at my cell phone 7766 as I choose at Outbound Calls on SIP trunk Calling Party Selection Originator so I received 6687766 the original calling party, this is good.

2-but when outside calling number try to call 7799 it can't forward the calls.

3- so I changed the  Calling Party Selection from Originator to Last Redirect Number(External) after that I am able to receive the forwarding calls on my cell phone but the problem here the calling number is 6687799 not the original calling party.

so what is the proper solution or workaround to solve this issue?

Please check this post. I think you need to use second or third method depending on your service provider settings:

Thanks, Vaijanath S.

thank you for reply @Vaijanath Sonvane, actually, I read this document before and I tried the second and third method, but unfortunately neither of both succeeded so let me explain to you what I have done :

phone A is calling number from outside  is 6687373

Phone B is called number from my DID range is 8317799

Phone C is a cell phone that receives forward calls number 0541407232

at second method

  request INVITE sip-header P-Asserted-Identity add "P-Asserted Identity:<sip:8317755@>"

where 8317755 is one my valid DID range and is IP of my CUBE interface that faces ITSP

when phone A called phone B and waiting till forwarding, I still can hear ringing without the appearance of any call on phone B or Phone C


at third method 

request INVITE sip-header Diversion modify "<sip:(.*)@(.*)>" "<sip:8317756@>"

when phone A called phone B and waiting till forwarding, I hear busy tone instead of forwarding the call


I take logs at the second and third methods you can find them in the attached files.

I want to make sure that the issue is not related to my configuration before going to ask my ITSP



I looked at the logs and I do not see complete call signaling. The call signaling below doesn't seem to be right for third method.



Can you please post full configuration of your CUBE router? Also, please post the logs from CUCM and CUBE for same call for third method.

Thanks, Vaijanath S.


kindly find the logs from CUCM and CUBE during the call and the configuration file for CUBE.


I looked at the logs and the INVITE that is being sent from your CUBE router to service provider doesn't include DIVERSION header.

It seems that the dial-peer configured with sip profile is not matching for these calls. Use debug voip ccapi inout command to see which dial-peers are matching and correct the configuration.

I forgot to mention in my earlier post that you need to enable Diversion Header on CUCM SIP Trunk in order for CUBE Diversion Header configuration to work. In CUCM, go to Device > Trunk and find the SIP trunk that you configured for outgoing calls. In the Outbound Calls pane, ensure that the Redirecting Diversion Header Delivery - Outbound check box gets checked.
