[cisco-voip] busy trigger and call transfer

[Eric Pedersen]

I thought the busy trigger only affected the line appearance on the phone, i.e. as long as there were other phones sharing the line that had not hit their busy triggers then the call would ring on those phones.

When you transfer you have the call on hold (1) and you're placing a new call (2).  Therefore when the extension rings it has hit the busy trigger and goes to voicemail.  When you increased it to 3, you allowed the call to go through.

This is normal.

I am seeing busy trigger behaviour that seems incorrect to me when calls are being transferred.

User A and User B both have line appearances for DN 1000 with a busy trigger of 2.  User A answers an incoming call to 1000, and then wants to transfer it back to 1000 so user B's phone rings.  However, when user A does this, it goes directly to VM even though user B has no active calls.  I increased user A's busy trigger to 3, but still saw the same behaviour.  To get user B's phone to ring, I had to increase her busy limit to 3 also, which makes no sense to me since she has no active calls.

Is CM behaving strange or am I just missing something?  It is CM 6.1(2).

Thanks,
Eric
