Asterisk SIP Trunk with CUCM Express, Disable Comfort Noise?

Hi All,

I have a sip trunk up and running with a CUCM Express, passing calls
fine except for a comfort noise error I’m getting on Asterisk:

NOTICE[7520]: rtp.c:788 in process_rfc3389: Comfort noise support
incomplete in Asterisk (RFC 3389). Please turn off on client if
possible. Client IP: x.x.x.x

I know Asterisk does not support comfort noise. I have “no comfort
noise” on all dial peers in the CUCM express and also have “no vad” on
all the voip peers. That should disable comfort noise but does not.
Could this be a bug in IOS or does anyone have any hints on what else
to look for?

Thanks.

Faxing with Asterisk 1.8.4 & T.38

And I use my own Asterisk FAX Gateway program:
http://messinet.com/trac/wiki/AsteriskFAXGateway

Asterisk + Patton ISDN2e gateway (UK)

I know I asked this some time back, and I got no response then, and
neither did someone who asked at the start of 2009 either by the looks of
it (other than a reply from me to use a PCI card!!!)

However I now have a client who’d bought one of these boxes and installed
ISDN2e – against my advice (because I got no feedback here, therefore
they’re junk with asterisk, right?)

However I’m currently stuck with it and it’s a right royal PITA to program
up by the look of it – I’ve done all the obvious stuff, and am now wading
through their 600+page manual, but ugh…

So if anyone has used one with asterisk as a bridge to ISDN2e in the UK,
would you mind sharing a config with me?

I have it registering (it pretends to be a SIP phone, it registers with
Asterisk), but when I try to send a call to it, it times out – I do see
debug on it’s console though – same when I send a call into it from the
PSTN side – I see ISDN debug messages, but no SIP activity.

And I thought Mediatrix units were bad – but at least they are relatively
easy to program…

Bah.

Any clues appreciated,

Thanks,

Gordon

Does anyone have a working asterisk 1.8.4 configuration and ITSP provider that they can recommend? We have been trying T.38 DIDs from our current ITSP, but we have been unable to make it work. I am more than happy to purchase new DIDs from a different provider if they will consistently work and are fairly priced.

Thanks for the suggestion Anthony.

I went ahead and signed up for a free DID from http://www.ipcomms.net/, but am still unable to receive faxes sent to that DID into FaxForAsterisk.

I have tried faxing to the DID from 2 different fax machines connected to different POTS lines. One fax machine is a Xerox Workcentre, and the other is a Brother Intellifax. Can you provide some more information about your setup? If you wouldn’t mind sharing your sip.conf settings, and maybe any other FaxForAsterisk related dialplan settings I would be greatly appreciative.

The faxes usually attempt to send, and appear to be properly switching to T.38, but usually end up failing with a “receive partial”.

I am open to any suggestions on resolving these issues. Thanks for any help you might be able to give!
