NO JOY cannot register with Fractel?

[buckrobbie80]

This is a noob question, Hi I cannot register with Fractel they had good rates for my area code so I signed up for a test account copied and pasted their free pbx settings they looked and did say they saw my iP address coming into their system but my firewall was blocking in the incoming packet that registers with freepbx. I noticed that the other providers Vitelity.com etc were specified in the Linux firewall in web min so I added the ip addresses that were in the outbound fractel freepbx configuration. But it still does not register are there other places/firewalls that I have to allow the ip's?? ip tables??? Thanks for any help you can give me. They haven't responded to my ticket yet.

Thanks,
Robert
