Thanks for the above, I was hoping to have replied earlier with a
success message buy alas, no joy to be had.

Could I be having some sort of DTMF issue? I noticed this in amongst the
console output once I set the console logging level to include dtmf

[2012-03-13 12:06:39] DTMF[24784]: channel.c:3976 __ast_read: DTMF end 'f' received on SIP/588-0000000c, duration 0 ms
[2012-03-13 12:06:39] DTMF[24784]: channel.c:4002 __ast_read: DTMF begin emulation of 'f' with duration 100 queued on SIP/588-0000000c
[2012-03-13 12:06:39] DTMF[24784]: channel.c:4138 __ast_read: DTMF end emulation of 'f' queued on SIP/588-0000000c

does the above look correct for an inbound fax?

Thanks in advance (again!)
