[asterisk-users] What causes SIP 486?

We have an asterisk system and Polycom phones that were provisioned by
someone else. They want to get call waiting to work, but for the life of
me, I cannot figure out why the Polycom is returning a SIP 486 Busy Here
when you call and the person is already on the phone.



I have the feeling there is a configuration in sip.cfg or mac.cfg that I
am overlooking. Any thoughts?



Calls per line key was set to 1, but I have set it to 2, and rebooted
the phone using sip notify Polycom-check-cfg and the extension for this
phone. Still no joy.



Yours,
