[Serusers] Problem registering ATA 186 with authentication.

Hello guys

Could anyone register an ATA 186 with sip version v.3.1.0 to ser using authentication?

I am running ser v0.8.12 on a RH9 machine. All equipments has public IPs.

I configured the following parameters in the ATA:

UID0:1000 PWD0:(the pass configured in ser) GkOrProxy:(ip address of ser) UseLoginID:1 LoginID0:1000@myrealm.com (where myrealm.com is the realm configured in ser) SIPRegOn:1

When ATA sends a REGISTER ser responds with 483 to many hops. So ATA does not register to ser.

I tried the same user with Windows Messenger 5.0 and ser responds with 401 unauthorized user and the nuance, so MSN sends the new REGISTER with all the information. Finally MSN does register to ser.

Any help on this matter is appreciated.

Pablo.
