I have noticed that when calling in to my FusionPBX from another SIP trunk the display on the SIP trunk phone says "600 201" not the number I had dialled. I have worked out that this is because Fusion sends a P-Asserted-Identiy header in the 200 OK. In this case the ring group extension and the extension that answered the call:
P-Asserted-Identity: "600" <sip:201@vox1.xxxxxxxx.co.uk>.
Is there a way of making this header contain sensible information for the caller or turning it off completely?
P-Asserted-Identity: "600" <sip:201@vox1.xxxxxxxx.co.uk>.
Is there a way of making this header contain sensible information for the caller or turning it off completely?
