[cisco-voip] Question about hold/transfer button not appearing on some calls

[Tim Reimers]

So then by "busy lines" do you mean 
 
- anticipated number of active calls on that line
 or 
- actual count of line appearances shared on phones, regardless of
incoming call count
 
I can see the logic in getting a count of lines higher than the actual
calls in progress.
 
But I had it set for 5 Max calls, and a trigger of 3, and with only TWO
calls on the line, wasn't able to transfer properly...
 
If I understand your explanation correctly, it seems like with 5 Max
calls, and only two in progress, I should have been able to have a
resource to transfer/hold with?

Basically lets just take a single line appearance 

set to 2 and 1.  Call comes in and your talking.  Second line calls in (
you now have two lines in use).  you will not have the option to
transfer that call because you don't have any lines available.

But if you had it set to 3 and 1 you would be able to transfer that
second line.

So on to your question:  Yes, I would set your Max lines to N+N(+1or 2)
that of your busy lines to avoid this issue.

Hope that makes sense

	I have a scenario going on where at times, the Hold/Transfer
button does not appear on the display. 
	This seems to happen when the user is on a call on 5510, and a
second call comes in to 5510. They then cannot place the call on hold to
take the second call, or do a transfer before taking the second call.

	Reportedly (from another cisco-voip user), when you have this
issue with no hold/transfer button, it's an "available resources"
problem, and you need to make more additional line resources available
in order for there to be a "place" to do the hold/transfer.

	Best I can determine, this is happening in the following
circumstance: 

	1. The DN is configured on multiple phones (12 in this case). It
is not the primary line on most phones 
	2. The Max Calls is set to 5  (currently) and the Busy Trigger
is set to 3 (currently). 
	Problem persists even at adjusted settings. 

	(Those values are 2 and 1 by default in our setup) 

	By experimentation with another similar setup elsewhere in the
system, we discovered that when four (4) phones had the same line, it
was necessary to set Max Calls to 16 and Busy Trigger to 4  in order to
get the "no transfer button/no hold button" issue to stop happening.


	What I'm trying to understand here is this: 

	1. Is it true that you always must set MaxCalls to four-times
the number of actual line appearances? and set Busy Trigger to the count
of shared lines?

	We don't have anything like 48 calls coming in -- even with 5
and 3 set, there should be PLENTY of resources available to do a
hold/transfer 


	Can someone explain this to me?
