Dear cisco team,
We're experienced problem with fax using ATA-186. We've tested either using fax relay or pass-through. When using fax relay, the ATA-186 can't disconnected the call to/from fax machine. And if we using fax pass-through, the fax machine only can receive half of the page with good conditions. Please advice..
For your additional information, we are using UCM 7.0 and router 3845 (using MGCP).
thanks fo your kid help
