Dear Benny, Thanks for pointing out. But actually i did not miss that. Actually i am facing problem when i am testing it from behind NAT (Not all places where NAT is but only one specific place) 1- Xten works in the same NAT. 2- I am using stun.xten.com as STUN Server. If i make call from a public IP network. In SIP INVITE i see X-NAT:0. But when i make call from a the specific NAT i am talking about, i do not see any header with X-NAT. In this case no SIP Responses reach from SIP Proxy reaches symbian_ua client. Is there any way i can look more into this issue?..may be by specifying Log File name in Init function of symbian UA?....what does it mean if i do not see X-NAT in INVITE message?

In SIP Log i can see X-NAT = 0. That means type unknown i hoped it would print symetric NAT. Please suggest?
