Phones are Aastra 57i. Carrier was Flowroute
.
Just had two call drops to the same number. While on the call, the person did not hear anything remotely resembling a fax tone. Anyone ever see this before?

Also, I'd like to add that sip_general_additional.conf shows faxdetect=yes, but I can't find anywhere to disable this in the GUI. Should I add faxdetect=no to sip_general_custom.conf?

 

[gregc]

I've posted at freepbx also. Can you add to that one there as well?

I did find this info but am not sure where I'd put faxdetect=no since I do need the feature. Is it possible to put faxdetect=no into outgoing routes/trunks somehow?

Just had it happen to me again.

What handsets are you using? I'm using Aastra 57i's.
