Hi All,
          I have currently connected an analog phone to an AddPac ATA. AddPac registers itself to the SER and there is noproblems with that. The AddPac can receive calls. But when I try to make a call from the analog phone it doesn’t go through. The proxy asks for proxy authentication. One thing I noticed is that for registration the "realm" field contains the IP address of SER whereas the realm field in the re-Invite contains the private IP address of the AddPAc. Is this the problem? If you any clue how to solve it.

Thanks,

Hitesh.
