Anybody able to get cisco 5350 register with openser using username and password.

Am using openser 1.0.1 with mysql authentication. When I try to send calls from cisco , I get 401 unauthorised.

Have made entries in sip-ua :

authentication username 90557 password 06575A751F1B504C5D42455C28 realm xxx.xxx.xxx.xxx registrar ipv4:xxx.xxx.xxx.xxx expires 3600

Under dialpeer :

session target ipv4:xxx.xxx.xxx.xxx

Where xxx.xxx.xxx.xxx is the ip address of openser.

Can anyone point out the problem?

Regards

DAN
