[Asterisk-Users] IAX and Firewall

[Joseph]

The problem are almost solved.
With regards to Teialx it appears that I was registered to their server
"co1" that worked in the past (but not now) as I'm suppose to be on
"co2".  So switching back to "co2" server solved the problem.

VOIPJET - one of their servers was down, so switching the server IP
solved the problem.
Is it possible to specify two or three alternate server in iax.conf just
in case once goes down so the system will try alternate server
connection?

I've tried connecting to Philippines from both providers and it appear
to me something must be wrong with the line to the Philippines, the
connection will not go through.
