The device in front of the SonicWall is a Cisco Router. Ping times to the ethernet interface of the router are good (~10ms). Also, having a user behind the SonicWall ping the PBX results in an average 20-30ms ping time. So it seems as though the lag is specific to SIP signaling (specifically the OPTIONS requests that asterisk qualify sends out). Unfortunately I can't really ask the client to dump their SonicWall (which we do not manage). On the SonicWall, I know it is configured for "Consistent NAT" and "SIP Transformations" are disabled. -- James >On Wed, Oct 22, 2008 at 11:35 AM, James Lamanna <[EMAIL PROTECTED]> wrote: >> 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. >> >> -- James >> _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
