[Jeff Johnson]

Sonicwalls from the TZ line and before line do seem to have a number of
issues with VoIP.

Hi,
I'm having an issue where some phones behind a sonicwall are
auto-congesting.
The status on "sip show peer" shows ping times anywhere from 80ms all
the way up to 1100ms.
PCs behind the same firewall have a ping time of about 30ms to the PBX
itself.

Does anyone know if the sonicwall is inserting delay into the SIP
signaling path and lagging the OPTIONS messages for qualify?

Thanks.
