[Asterisk-Users] Asterisk configuration inside a DMZ w/SIP

[Brian D'Arcy]

Hi Russ,

Thanks for your feedback!  I hadn't received any other responses from
anyone, so I was starting to worry that I was one of the few having
these erratic issues.

I might ping Sonicwall, being a good customer and all, maybe I can get
some information out of them.  I've always liked using the sonicwall for
ease of use and administration (and reliability), since I'm overworked
as it is, but if I have to get rid of it to make this work, I'm not
against it.

On a side note, I tried IAX2 last night for the first time using
IAXPHONE.  HOLY CRAP I'M IMPRESSED!!!  Everything just *works*, period.
I might just use softphones until IAX hardphones are released and say
screw SIP.

If anyone else is having SIP nightmares and you have a flexible
deployment schedule, I highly recommend giving IAX a shot!!

Thanks again for the comments, Russ.

We've discovered that certain versions of the sonic wall products do 
strange things with SIP.   For example the TC170 with standard firmware 
works fine (Public Asterisk, Polycom IP600 behind the Sonic wall). 
Upgrade that box to the enhanced version and suddenly transfer and hold 
stop working.

It's not just SIP, either.  SNTP on the IP600 through the Sonic Wall 
gear changes the time by 10 hours.

These things have been reported to Sonic Wall, but no word on a patch.
