No fax destination in IVR context

General Help
1

Hello all,

I’ve set up fax detection on an inbound route. The next destination is an announcement, which is then followed by an IVR.

If fax detection works before the call is transfered to the IVR, then everything works fine.

However, if fax detection is triggered after the (fax) call has been transfered to the IVR, asterisk can’t find the fax destination in the IVR context and fails:

res_fax.c: FAX T38 detected but no fax extension in context (ivr-1)

Is there a workaround for this? By workaround I mean have the IVR context define a fax extension, because other solutions (like increasing the fax detection timeout for the route) is not acceptable. Thanks!

This is on FreePBX distro 6.12.65-27 with asterisk 11.

No once the call leaves the Inbound Route after the timeout it wont route back to a Fax Destination

Hello Tony,

Thank you for your immediate reply. Is it possible to do this by writing a custom context for ivr-1? I believe the only entry missing is something like:

exten => fax,1,Goto(${CUT(FAX_DEST,^,1)},${CUT(FAX_DEST,^,2)},${CUT(FAX_DEST,^,3)})

Or am I being too naive here?
