Hi,

i have a problem with dialing any extension (incoming calls works) from IP phone Aastra DBC 4422, i am using firmware R6H, i have captured traffic on server side and there is "proxy authentication required" error. I have tried in config file of phone with proxy server address and without it, but problem is always the same (error above). I am assuming that this is firmware problem (not fully SIP compatible) i know there is new firmware R7M but i cant find it on Internet.

Please if someone can provide me a new firmware for Aastra DBC 4422 (DBC 422 02/01001).

Thanks in advance.

Best regards.
