Hi,
I'm running a NIST SIP proxy on my PC, which listens on TCP and UDP on port 4000.

I'm trying to setup the emulator SIP settings ( settings -> Connection -> SIP settings)to create a registration but it always fails.

As far as I can guess, the problem is in the settings themselves and the SIP engine does not even try to connect over TCP to the Registrar.
(I verified that the emulator can connect to the listening port on my PC).

Could anyone please provide settings that are known to be working and to succeed in registering to a SIP registrar?

My current settings are:
-----------------------
Profile name: Profile
Service profile: IETF
Default Access Point: Winsock
Public user name: sip:none@ignored.com
Use compression: No
Registration: When needed
Use security: No
Proxy server
Proxy server address: sip:[my PC host name]
Realm: None
User name: None@ignored
Password: None
Allow loose routing: Yes
Transport type: TCP
Port: 4000
Registrar server
Proxy server address: sip:[my PC host name]
Realm: None
User name: None@ignored
Password: None
Transport type: TCP
Port: 4000

Please correct me if one of the settings is wrong or suggest new settings.

Thanks
