I'm in pain.

We are moving to a SIP based VOIP system and for whatever reason, we could not get our hosted Asterisk solution to work with our Sonicwall. Our VOIP provider gave up and is recommending an open source vendor, pfSense.

A little background:

We have about 30 users in our network.
We use a few IPSec VPN connections for remote networks.
I would like, but don't need, application layer filtering.
We're active internet users, so properly traffic shaping is probably a concern.

How can I tell if an open source firewall will handle VOIP setup smoothly with a hosted Asterisk system?
