Thanks for your continued help.
We are on the same page I think, the whole deal should be to determine if it is the phone or the system. But in all honesty I personally do not think that SIP even works that way where caller info would be sent a second time. Well lets just say I have never seen that.
Just to be specific in my case I will use "sip set debug peer". I will do some specific testing and very soon and report back.
Thanks again.
