Hi Mark, I'm having problem with fax detection on my Asterisk box. My config is like this: PSTN T1 <==> Asterisk (*) T100P (2 cards) <==> PBX Everything works fine for voice and incoming fax but out going fax got this error: -- Starting simple switch on 'Zap/48-1' -- Executing Dial("Zap/48-1", "IAX2/myusername@NuFone/16509300206") in new stack -- Called myusername@NuFone/16509300206 -- Call accepted by 66.225.202.72 (format ULAW) -- Format for call is ULAW -- IAX2[NuFone]/2 stopped sounds -- Redirecting Zap/48-1 to fax extension Mar 4 12:11:58 WARNING[1217602880]: app_dial.c:293 wait_for_answer: Unable to forward frame -- Hungup 'IAX2[NuFone]/2' == Spawn extension (outbound, fax, 0) exited non-zero on 'Zap/48-1' -- Executing Dial("Zap/48-1", "Zap/g1/fax") in new stack -- Called g1/fax -- Hungup 'Zap/1-1' == Spawn extension (outbound, fax, 1) exited non-zero on 'Zap/48-1' -- Executing Hangup("Zap/48-1", "") in new stack == Spawn extension (outbound, h, 1) exited non-zero on 'Zap/48-1' -- Hungup 'Zap/48-1' Is there something wrong here?
