I'm trying to set caller presentation to prohibited and I'm having slight problems doing it. Using a machine that has a Sangoma facing my Telco works but when using an asterisk that talks to the first machine using SIP it does not work. I suspect that SetCallerPres is not transitive, ie it's not communicated between SIP peers but need to be set at the actual machine having the Sangoma card, correct? Anyone have a workaround for this? How should I set callerpres to prohib when doing SIP to SIP calls? Or when calling via SIP and then out on the PRI, how can I set callerpres on the machine originating the call? Thank you Regards, Kristian
