Hi list, I am trying to figure out, after abandoning trying to get iaxmodem working in FS, if it is possible to use t38modem to connect FS to Hylafax, mainly for the purpose of sending and receiving non-t38 faxes via an ISDN card or non-t38-aware gateway (I'm currently using our Mitel 3300 as the gateway and voice calls between the two systems are fine). I have managed after a lot of effort to get t38modem compiled and running, and it seems to react to incoming fax calls coming in via the Mitel gateway from a normal fax machine, but the fax machine does not hear any reply to its initiation tones and the call hangs up in the end. Ivan on this list has suggested that I don't really need to do the gatewaying as t38modem can work with audio over SIP as well, so I tried removing all the t38 lines from the dialplan but with no success. My fax dialplan looks like this: <extension name="from_mitel" > <condition field="network_addr" expression="10.10.0.2"/> <condition field="context" expression="public"/> <condition field="destination_number" expression="(^1001$)"> <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="fax_enable_t38_request=true"/> <action application="set" data="execute_on_answer=t38_gateway peer"/> <action application="bridge" data="user/t38modem@${domain_name}"/> </condition> </extension> t38modem is invoked thusly: t38modem -tttt -o /var/log/t38modem.log --no-h323 -u t38modem --sip-register t38modem@192.168.20.245,password --sip-listen udp$127.0.0.1:6060 --ptty +/dev/ttyT38-1 --route "modem:.*=sip:<dn>@192.168.20.245" --route "sip:.*=modem:<dn>" Where 192.168.20.245 is the ip of the FS box. Any ideas? I can provide logs if required. Thanks, Alex -- This message is intended only for the addressee and may contain confidential information.
