The main problem is that calls seem to drop randomly. Since most of the
calls they do are conference calls this is not acceptable. Sometimes
they will have to redial constantly.
We are using the latest Asterisk. The server does not have any card,
it is a pure IP system. We use IAX2 to send calls to Teliax but usually
receive them via SIP. All extensions on the server are SIP. We have
tried using ulaw, alaw, g729 and gsm to send and receive calls but still
some get dropped. The customer has a 10mbps link to the Internet so
congestion is not a problem here.
What would be the best way to determine where the call is being
dropped? What tools should I use to diagnose this problem?

Have you tried their tech support? How are you configured that you're
receiving calls via iax and sending them outbound via sip? Why would
you do both and not one or the other? SIP has historically been more
reliable with Teliax.
A 10mbps link doesn't guarantee anything. What's a traceroute to Teliax
look like? Ping times?

I use Teliax with my SOHO Asterisk server. I had nothing but problems
with IAX on Teliax. Changed over to SIP and it's been flawless. Oh
once in a while I get congestion from Teliax, but once a call is up, you
can not tell it's VoIP since I changed over to SIP from IAX.
