I had weird issues when using a Sonicwall, gave up. Stuck in linksys
running
dd-wrt firmware running on a separate VLAN... no issues since

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.
