Sample Settings for Asterisk with iEtherSpeak (ZIPTrunk) that worked for us:
Note: Mindwatering does not endorse EtherSpeak. This information is provided for sample configuration only.
To get our trunk open, we:
1. Made a "hole" in the firewall to their IP address and opened up ports UDP 2050 & 2051 as a forward to our Trixbox/Asterisk server's internal IP. You also need a whole bunch out (which were open anyway from internal).
2. Created a SIP Trunk and Route Out and a Route In.
3. Updated the sip_nat.conf which seemed to be necessary to get the outgoing half of the trunk working.
sip_nat.config File Additions:

Notes:
What got us were messages. We kept getting "circuits not available" and "invalid number" messages. We ended up doing a console into the server and looking at the SIP log messages while in debug and placing calls from both directions. How to get started. (Hint: type help sip in the CLI for a list of commands.)
# asterisk -r
CLI> sip set debug on
...
CLI> sip set debug off
CLI> exit
# exit
Also, the bulk of our issue was actually a dialing pattern out. So start with a good dial out rules to add the 1 necessary in this case. That way you are only testing the trunk and not going down a very lengthy hole troubleshooting trunk settings needlessly.
