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

[Scott Voll]

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
