Hi! Not sure how long I have the problem, since I really don't send many faxes, but today I need to send one, and it does not work... I use HylaFAX 6.0.6-8.1 from Debian repositories and IAXModem 1.2.0~dfsg-3 even from Debian repos. IAXModem is configured so: device /dev/ttyIAX owner uucp:uucp mode 660 port 4569 refresh 60 server pbxint.lucabert.intra peername 0049351xxxxxxx secret myverypassword cidname Familie Bertoncello cidnumber 0049351xxxxxxx codec alaw I tried (to debug) to send me a "fax" to my mobile phone. The number will be called, but if I answer, instead of hearing the usual "sound" of a fax, I only hear a "wait tune". In Asterisk I see: -- Accepting AUTHENTICATED call from 192.168.10.3:4569: -- > requested format = alaw, -- > requested prefs = (), -- > actual format = alaw, -- > host prefs = (alaw), -- > priority = mine -- Executing [0177yyyyyyy at fax-out:1] NoOp("IAX2/0049351xxxxxxx-2884", "") in new stack -- Executing [0177yyyyyyy at fax-out:2] Verbose("IAX2/0049351xxxxxxx-2884", "2,Call from FAX") in new stack == Call from FAX -- Executing [0177yyyyyyy at fax-out:3] Dial("IAX2/0049351xxxxxxx-2884", "PJSIP/pbxfax/sip:0177yyyyyyy at tel.t-online.de,,R") in new stack -- Called PJSIP/pbxfax/sip:0177yyyyyyy at tel.t-online.de > 0x7f8ec402c000 -- Strict RTP learning after remote address set to: 217.0.5.212:27590 -- PJSIP/pbxfax-00000086 is ringing > 0x7f8ec402c000 -- Strict RTP switching to RTP target address 217.0.5.212:27590 as source -- PJSIP/pbxfax-00000086 is ringing -- PJSIP/pbxfax-00000086 answered IAX2/0049351xxxxxxx-2884 -- Channel PJSIP/pbxfax-00000086 joined 'simple_bridge' basic-bridge <9c5b5ca2-d4d9-42e9-b5f8-9532e09cc360> -- Channel IAX2/0049351xxxxxxx-2884 joined 'simple_bridge' basic-bridge <9c5b5ca2-d4d9-42e9-b5f8-9532e09cc360> > 0x7f8ec402c000 -- Strict RTP learning complete - Locking on source address 217.0.5.212:27590 -- Channel PJSIP/pbxfax-00000086 left 'simple_bridge' basic-bridge <9c5b5ca2-d4d9-42e9-b5f8-9532e09cc360> -- Channel IAX2/0049351xxxxxxx-2884 left 'simple_bridge' basic-bridge <9c5b5ca2-d4d9-42e9-b5f8-9532e09cc360> == Spawn extension (fax-out, 0177yyyyyyy, 3) exited non-zero on 'IAX2/0049351xxxxxxx-2884' -- Hungup 'IAX2/0049351xxxxxxx-2884' HylaFAX said: Aug 16 18:34:37.51: [26819]: SESSION BEGIN 000000371 491773218409 Aug 16 18:34:37.51: [26819]: HylaFAX (tm) Version 6.0.6 Aug 16 18:34:37.51: [26819]: SEND FAX: JOB 39 DEST 0177yyyyyyy COMMID 000000371 DEVICE '/dev/ttyIAX' FROM 'lucabert <lucabert at lucabert.de>' USER www-data Aug 16 18:34:37.51: [26819]: <-- [12:AT+FCLASS=1\r] Aug 16 18:34:37.51: [26819]: --> [2:OK] Aug 16 18:34:37.51: [26819]: DIAL 0177yyyyyyy Aug 16 18:34:37.51: [26819]: <-- [16:ATDT0177yyyyyyy\r] Aug 16 18:34:52.66: [26819]: --> [10:NO CARRIER] Aug 16 18:34:52.66: [26819]: SEND FAILED: JOB 39 DEST 0177yyyyyyy ERR [2] No carrier detected Aug 16 18:34:53.66: [26819]: <-- [5:ATH0\r] Aug 16 18:34:53.66: [26819]: --> [2:OK] Aug 16 18:34:53.66: [26819]: SESSION END Any idea what can be the problem?
