SnonONE v5.0.7 MacOS & Patton SmartNode 4554

When setup with voicemailbox enabled I am redirected to the right mailbox and message is delivered to the configured mailaddress.

With voicemailbox set to FAX I get an error "488 Not Acceptable Here."

Can't really say anything about Patton... However the PBX does attempt to switch to T.38, so a lot of things went right before this step. The G729 codec cannot be the problem. I don't understand why Patton would reject the T.38 re-INVITE. Maybe there is a way to get a more detailed log from the gateway why it does that.

Thanks to the great support of Patton, the mistery is solved.

It's great to define an alternate voip profile but doesn't help when you don't use it ;(

 

in 'context cs interface sip' it missed the line 'use profile voip VOIP'. The gateway was always using the default voip profile which only allowed g711 but no t38.

 

Attached the running config if it can help someone.
