[Asterisk-Users] Zultys Zip2 (SIP)

[Terence Parker]

Has anyone ever tried getting a Zultys ZIP2 phone to work with Asterisk? We have a few of these lying around in the office but are having difficulties getting them to dial out - authentication error. Curiously though, the Zip2 initially logs in correctly and is still able to receive calls.

The error I get when a ZIP2 phone attempts to dial:

NOTICE[245776]: File chan_sip.c, Line 4802 (handle_request): Failed to authenticate user Test<sip:[EMAIL PROTECTED];user=phone>;tag=178bc-2289b

I have entered the username/password correctly, but my guess is the phone probably does its authentication in a different way. Zultys claim the phone is fully SIP compliant and very generic - but I have been increasingly finding them working well only with their own gateways (which are extremely expensive).

For those not familiar with the Zip2, I have two screenshots showing the relavent web based configuration screens - you can find these at http://parker.com.hk/zultys (don't want to fill up your mailbox with large attachments).

I have tried several combinations, including using AES for the authentication too - but with no luck. Could it be that this phone just doesn't work with asterisk?

Thanks!
