I've got a Hipath system that can't transfer using an analog line. I'm at another in my area, came here just to verify a supervised transfer is simply hookflash, dial the extension, announce the call, go on hook. At the remote site having trouble, the analog line attempting the transfer will ring back after going on hook, connecting to the original caller. Compared settings, everything looks the same. I wonder what could cause this? I didn't think transferring could even be restricted.
