Hi,

I’m new to freeswitch and I’m trying to set up 2 polycom phones running 4.0.2 firmware to share a line. I followed the wiki pages http://wiki.freeswitch.org/wiki/Shared_Line_Appearance and However, whenever I pick up an incoming call or try to make an outgoing call on one of the shared lines, the other line doesn’t detect that the line is in use and I get a massive dump of 481 and 482 errors dozens of times. I have no idea what is causing this behaviour, any help would be greatly appreciated
