Summary:                    Wrong Caller ID on Sip Channel when have a lot of
hanging up call
Description: 
Our system working as a simple IVR & ACD:

PSTN <======> MediaGateway <==SIP==> Asterisk <===SIP===> IPPhone

CDR Table has more than 2.5M records. And today (01/01) our crontab runs
the cleaning task that leads Mysql get very slow. So when call hangup, it
takes long time to write CDR and system have a lot of dead call (with load
of 80 call concurrent, after 2 hour we got about 3000 dead call that insert
CDR)
And when system reach 500 dead calls, all callerid send to IPPhone is
wrong.

Agents sometime report the wrong callerid when system in high load (200
calls), but only today I can reproduce the bug so I suppose this is the
glue.
I thought this relate to https://issues.asterisk.org/view.php?id=16054,
but I set session-timers=refuse and "sip show channels" show the normal
number of dialogs.
