Supress original number

Recommended Posts



We have a main number 012345-0 with some internal extensions 1 to 9. For all outbound calls we want 012345-0 to be transmitted. That actually works but we surprisingly noticed that when we call one spezial external extension our internal extensions are transmitted. We don't know if this is the only external extension where this happens. We took a look at a SIP INVITE packet and noticed that internal extensions are transmitted in the P-Asserted-Identity field which should be deleted when the packet leaves some trusted domain but only in case there is a Privacy header whith some spezial field present in the packet. How to achive that?
