Call Forwarding SIP Trunk

Jump to solution

Hi Guys,

I am using NetVanta7100 PBX and it is configured with SIP Trunk account.

We have 3 parties involved

A-Party - PBX User

B-Party - Mobile Subscriber

C-Party - Forwarded Number (Mobile Subscriber)

A-Party put unconditional forwarding on his handset

B-Party called A-Party,

A-Party generated 302 Moved Temporarily with C-Party Number details to PBX

PBX generated a new invite to C-Party having From header of B-Party from trunk account and SBC block it.



I want From header  to be of A-Party and it should appear A-Party is generating a call from trunk


Regards,

Sim

Only solution but it requires the user to configure Find-Me Follow-Me, is under the FMFM Advanced options at the top, is to see the External Caller ID Number.

Unfortunately there is not a global way of doing what you are trying to do.

Two options that you can do to try to work around.

(1) Change all your ANI (Caller ID) to one main number

You can go to Voice / Trunks / Trunk Accounts and select your SIP TA. Select the ANI Substitution tab and enter following:

· Match Template = $

· Substitution = Your 7 or 10 SIP DID number

· Name: Change outbound ANI

(2) Manually enter one entry for each user who forwards a call

This will only work if your SIP Trunk provider is accepting calls from all the Subscriber numbers at your company.

You can go to Voice / Trunks / Trunk Accounts and select your SIP TA. Select the DNIS: ANI Replacement tab and enter following:

· Match DNIS Template: C-Party Forward Number

· ANI Replacement: A-Party 7 or 10 digit DID number

· ANI Name: A-Party Name

Let me know if you have any questions.

What most people want is for the From header to be B-party so that the subscriber knows who is calling rather than just that it's a forwarded call.  But they want the SBC to allow it.

You may need to work with your carrier but this should be doable *IF* the 7100 is capable of authenticating as a trunk.  The contact header and From can be different.  Otherwise you'll need to force the caller-ID to be that of a valid user.
