Summary:                    All SIP users InUse counters reset  to zero(even if
they are on call) during sip reload
Description: 
Suppose a user is on a call whose call-limit=2. "sip show inuse"  shows the
inuse counter of the user is set to 1. But after reloading sip (the user is
still in conversation and call is up) the "sip show inuse" command shows
that its inuse counter is set to zero. It shouldnt do that. i have seen
inside the code in chan_sip.c that while doing sip reload, asterisk
destroys all the users (not peers) by freeing the memory allocated for all
users and destroying their channel variables. As it destroys all the users,
their inuse counter is also lost. So if a user whose call-limit was reached
before the sip reload, after doing sip reload, he can make more than
allowed simultaneous calls.

I have tested and can repeat this behaviour on any version of asterisk
(1.4.2, 1.4.18, 1.4.19, 1.6.0beta5)

I am using a Dell Pentium PC with CentOS4 Installed on it.

This bug has great importance for us as we have users with call-limit=30.
So if a user has inuse counter reached to 28, and then a one of my script
automatically issues a sip reload, the inuse counter is reset to zero and
the user is able to make 30 more simultaneous calls instead of 2. So i am
setting the severity of this bug to major.
