It works very well. Try it you'll be shocked. /b On Jun 4, 2010, at 9:46 AM, Kristian Kielhofner wrote:

Brian,

Can you be any more specific? I'd love to do some testing...

Its in mod_spandsp now and yes its been tested but I'm sure their are some more corner cases that aren't accounted for. /b On Ju

How is t38_gateway used?

Is it fully automatic and autodetects between all possible cases to activate when needed (G711<->G711, T38<->G711, G711<->T38 and T38<->T38), or does one has to specify which leg has T.38 and activate the gateway only when needed?

Thanks, François.

You could use FreeSWITCH in proxy media or bypass media without any specific T38 support right now... On Fri, Jun 4, 2010 at 11:17 AM, Peder <peder@networkoblivion.com> wrote:

Is T38 forced on if you do this, or does it just enable the feature if it sees it in a reinvite?  We have a bunch of fax lines w/ SPA2102 and then we use Cisco routers as PRI-SIP gateways.  Some of the people use the lines for phone too, so I need it to support T38 and regular g711 calls.  Right now we just point the SPAs direct to the Cisco gateway and it works fine, but we lose all accounting capability, voicemail, etc that we want/need.

Looks pretty cool, will try that! A few more questions: - How does it work (more or less)? - Will normal bridges (no fax) work when t38_gateway app is called? - Can it fallback to audio fax if the peer does not support t38? - In passthru case, what happens if t38_passthru is not defined and the peer reinvites with t38 (any reason for having to set t38_passthru?)?

So to receive a fax (transmitted via t38 from an audiocodes gateway or ITSP) as a tiff file I would do something like: <extension name="tdm_to_sip"> <condition field="destination_number" expression="^1234$"> <action application="answer"/> <action application="t38_gateway" data="peer"/> <action application="rxfax" data="blah/blah/receivedfile.tiff"/> <action application="hangup"/> </condition> </extension> ?
