Did it ever work, or did it just stop working?

What type of trunks are you suing for incoming calls and do they (the VoIP provider) support T.38 ?

 

[ahramov]

Earlier he worked. Incoming were accurate.
Codecs g711. The operator says that supports T.38 available.

If it worked previously, then what changed, at your location, just before it stopped?

Get a wireshark capture, filter for SIP and examine the t38 re-invite. If you need help, post the capture here.
