[OpenSIPS-Users] OpenSIPS Billing Discrepancy

[Ryan Mitchell]

Accurate billing is always difficult, surprisingly so.  It's quite common
from my experiences to have billing disputes because some stupid BYE
message was never recorded.  Few thoughts:

1. despite the transaction handshaking of SIP, hangup messages can and do
get lost (or were never sent).

2. lost not always by Opensips or your network, but *somewhere* in the
chain from caller to callee.  I often make it a point to capture & save
*all* SIP packets in & out of my switches, so I can audit and cover my butt
later as needed.

3. SIP timers (and if handling media, rtp timeouts) can be vital.  TCP
helps if you can use it.
