I am having difficulty in that no caller id information is being sent as Remote Party ID on a pjsip trunk. I have the situation where a sip trunk to my voip provider carries several different numbers. I use the extension trunk CID field to designate the particular CID number to be used by that extension which should be sent out in the invite message. If the VOIP provider does not receive a CID number he inserts the master CID number for the trunk.
There is no difficulty with a chan_sip trunk as setting senderpid=yes causes this to happen.
From my research I beleive that adding trust_id_inbound=yes to the endpoint conf file may resolve this problem. Is there a simple way I can do this?
