Register Mitel hand set to Sonus SBC (SIP)

[DevilWAH]

Hi,

has any one ever successful registers a mitel 5312 or similar model to a SONUS SBC?

we have at one branch site only a sonus SBC1000 and I would like to register a mitel hand set to it in sip mode.

I can get in OK and configure the mitel sip user name and password. and have followed the SIP configuration on the Sonus, but in the sonus logs i see  "username="null" password="null"

If any one has set some thing like this UP I would be interested to hear how

cheers
