[cisco-voip] ATA186 Problem receiving external faxes

[Enrique Ayesta Perojo]

Hello, we are having an strange problem with CME and ATA186-l1 using a Brother 
MFC-465CN (14400bps, so it should work correctly with the provided ATA). With 
the actual config i can send Faxes without problem, but i have problems 
receiving them. If i call from an internal extension the fax answers the 
call, but if i call from an outside number the fax rings but then it doesn't 
answer.

I don't know where to look at, i think it could be something related to 
different phone rings with inside and outside calls, but i'm not really 
sure... I think that the fax should answer and then start the negotiation...

Any ideas?

Thanks
