linksys 942 & multi inbound calls

[d1rage5]

Does anyone know how to set this phone to allow more then one inbound call.
right now ext 1 is setup and i can receive a call but if another call comes in it goes to voicemail.
I i am on the one call and place the call on hold i can make a call to another ext and outside line.
the ext2, ext3, ext4 are all enabled but the use a different port like 5061, 5062 and 5063.

i tried setting the port on two extensions to the same port 5060 to test but that was a no go.

fixed my own problem...

After more testing and test and testing. I thought i would take a look bacl at the setting on 3cx under the extensions.

Destination Unreachable / Forwarding <<<

then Phone Busy

set the first setting Busy Detection to use phone and NOT use PBX stats

Thats it workie workie now.
