Steve,

I couldn't get it to do so for inbound faxes, I had to transcode as it 
only seems to work with T38 input, but it is now working:

<extension name="from_mitel" >
<condition field="network_addr" expression="10.10.0.2"/>
<condition field="context" expression="public"/>
<condition field="destination_number" expression="(^1001$)">
<action application="bridge" data="{sip_execute_on_image='t38_gateway 
self nocng'}user/t38modem@${domain_name}"/>
</condition>
</extension>


However on the outbound side it seems to be insisting on sending audio 
(ALAW/ULAW), but even if I don't transcode the fax never completes.

T38 modem keeps giving me:

2011/11/11 09:51:03.494  Media Patch:0xb597db70 RTP_UDP Session 1, 
Control port on remote not ready.

Whatever dialplan I try I can't seem to make this go away.

Anyone got t38modem working outbound?

Cheers

Alex
