Yeah that seems unexpected.

Can you attach the same log, but including "sip set debug on" and "fax set debug on" ?

> When a fax is detected (faxdetect=yes in sip.conf) the 'h' extension is run immediately, just before the 'fax' extension is run. The 'h' extension is then NOT run after the 'fax' extension finishes. So it's being called at the wrong time.
> Please see attached trace and follow the call with channel "SIP/pn1-00000193". You'll see the fax being detected here:
> [2013-12-04 10:16:09] DEBUG[13541] chan_sip.c: Fax CNG detected on SIP/pn1-00000193
> then the 'h' extension:
> [2013-12-04 10:16:09] VERBOSE[13541] res_agi.c: <SIP/pn1-00000193>AGI Tx >> agi_extension: h
> then the 'fax' extension:
> [2013-12-04 10:16:11] VERBOSE[13541] res_agi.c: <SIP/pn1-00000193>AGI Tx >> agi_extension: fax
> then the call finishes, but the 'h' extension is not then run:
> [2013-12-04 10:16:59] DEBUG[13541] channel.c: Hanging up channel 'SIP/pn1-00000193'
> Here's the extensions.conf entry:
