SIP Trunking Broken By XG V16?

DavidPeterson

I'm trying to migrate from a Sonicwall to XG115 V16.  I've been running two different SIP gateways through the Sonicwall from the same PBX, serving two different tenants.  When I move to the XG I get one way audio problems and my SIP soft phone app on my Android can no longer register through the XG. 

I tried the "system system_modules sip unload" command which didn't seem to help.  The Allworx PBX automatically rewrites the WAN-bound packet's internal address as the public address for return traffic to use, and all I ever did on the Sonicwall is enable what they call Consistent NAT.  Interestingly, when I effectively disabled that by telling it the public address to use was actually the private IP I got two way audio going on the desk phones, though calls would drop after a few seconds.  The soft phone would register but not have audio either direction.  I may be mixing up the combination of things I did, but bottom line is I need some feedback on if there are issues I'm beating my head against the wall on, or some settings I need to know about.  I saw one article referring to disabling DOS setting, but did not see that in V16.

Any ideas?

    Hi David, I can't offer any help regarding SIP as thats outside my knowledge level.  But as far as the DOS settings, look under "Protect/Intrusion Prevention" and then the far right tab has all the DOS settings.  Hope that helps.

     

    Thanks

    As you did, get rid of helper module.  Normally things like that will make matters worse.

    Make sure you have a network rule, allowing RTP traffic to the outside.  (allow rule, source IP=PBX, UDP , source ports=UDP portrange of PBX)

    I'm new to Sophos, but do I need a rule to let something out?  That's hardly normal firewall behavior as they default to allowing everything out.  Everything else gets out.  I do have all the same rules I had on the Sonicwall on the inbound.  I was working late at the main office with a two hour drive home so didn't stick around for packet captures, but definitely need to learn the logging functions.
