Hi

Appreciate any help out there in setting up sip trunks from Eir (Irish Provider) just cannot get them to work on the SL2100.

I can get other sip providers to work on the SL2100 but not Eir. Eir is the probably one of the biggest ISP and telecom suppliers in Ireland.

Eir sip credentials that I have will work on the Panasonic NS and NCP systems so its not an eir issue.

The only difference on the Panasonic was to change the setting "Un-Register Ability when port INS" when I disable this on the Panasonic Eir SIP trunks worked.

At the moment I can see from the Wireshark trace the information is been sent to the ISP but is coming back "575 Status :401 Unauthorized"

Any suggestions where I can look
