Without throwing the provider under the bus it might be good to document this as a "known issue with a workaround." We would just need to add a provider page and link it here: http://wiki.freeswitch.org/wiki/SIP_Provider_Examples Thanks! -MC On Fri, Sep 14, 2012 at 4:46 AM, Rob Moore <Rob.Moore@aeriandi.com> wrote:
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.*** *

** **
Hi All,****
** **
I’m having a little trouble with ‘presentation numbers’ with a new provider I’m in IOT with this week.****
** **
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. ****
** **
Thanks****
