Hi Everyone, For those who are interested I found a way around this issue. I'm not sure if this is the correct way to produce this result but it worked. The problem I had was that I could set the Freephone number I wished to present but the P asserted ID would overwrite this with the other standard number I was attempting to send. So to resolve the issue I had to disable all CID, use effective_caller_id_number to present my Freephone number (this adds the number to your from header) then I used sip_h_ to add the P-Asserted-Identity manually. <action application="set" data="effective_caller_id_number=+448000000262"/> <action application="export" data="sip_cid_type=none"/> <action application="export" data="sip_h_P-Asserted-Identity= <sip:+445600000262@fixsipbizzle.org> "/> Hope this helps anyone else who ever has to provide this unusual setup.

I'm trying to recreate the following Invite as the calls pass through our dialplan to this provider but there are issues with trying to get a different CLI into the From and P-Asserted-Identity headers. When presenting a Freephone number (for example) we need to still present the regular number that would be used by this extension in the P-Asserted-Identity whilst passing the number we wish to have presented in the From header. Currently we are not using Gateways so we cannot resort to using <param name="caller-id-in-from" value="true"/> (although I expect this won't do what we need in this case) so I've looked at altering the channel variables sip_from_user,sip_full_from and sip_full_uri using set and export dial plan apps but none of these seem to have any effect so I guess these variables must be read only. I'm sure this must be simple, but can't for the life of me work out what I need to do. Below is an extract from an example header from the provider I am trying to recreate, I've also added a copy of the Dialplan extension I am using to test. If someone can tell me what I'm getting wrong I would really appreciate it.
