Hi!  I have a SonicWALL tz 150 with Standard OS.  My VOIP phone company on the island issues my a 2 port LinkSys ATA for my voice service.

I found this Experts Exchange session that was VERY close:  HomeNetworkingTelecommunicationsIP TelephonyVoice Over IPInteresting Issue...VOIP Dropping in Exactly 5 minutes

What is happening here is the ATA connects and registers with the PBX.  The phone works for 15 minutes.  Then the phone is unreachable for incoming calls.

In exactly 15 more minutes the ATA registers again with PBX and is active again for another 15 minutes.  This continues.

The VOIP technician says that I need to increase the UDP connectivity to more than 30 minutes.  It is the firewall that is disconnecting the ATA from the PBX.

does anyone know how to do this on a SonicWALL TZ 150 standard OS?  The support stopped a year or so ago so I cannot request help from SonicWALL.

as far as i know, there isn't an option to change UDP timeouts on a standard OS.  i checked with a tz 170 that i have sitting around.  i could change the tcp under firewall > advanced and under the advanced tab of any of the firewall rules.

however, under firewall > voip.  what options are enabled here?

I found the same.  From one of my friends and other research done on the web they suggested enabling "consistant NAT".  I will try that and let you know what happens.
