I’ve gotten a pair of Vizufon CIP-5500s working with FWD, mostly to make sure I didn’t have defective products. I also know that Vizufon claims no compatability with Asterisk as of yet.
Regardless, I like making things work with eachother. So far I can get the phones to register against Asterisk with SIP, and they can get INCOMING calls. Where I’m stumped is trying to use them to make OUTGOING calls, even within the PBX to other non-Vizufon phones, not bothering with external lines.
On the server, it complains that the SIP user is not authenticated. With or without Auth ID enabled, it continues to report the same error. It also complains about error 415 “Unsupported Media Type”, however there is no way I can see on the phone’s menu system, to change codecs or anything in the INVITE string.
Just wondering if anyone else is playing around with these and made some headway on placing outbound calls.
