Hi, I created a generic trunk with the options shown in the screen shot. I requested that the remote party ID should contain the "caller" info and I also setup custom outbound options for the "called". Yet, the provider claims that he does NOT see ANY Remote Party ID header on his CISCO SIP gateway!? I then checked the 3CXPhoneSystem.trace.log and I see the following header for the test call I placed: I scanned for "Remote" in the log and nowhere do I see a remote party id being generated? Is this a bug? Are all of these options ignored? If so, why can I set them?
