For you to use your Grandstream ATA you need to fill in these sections of the menu within the Adapter.

Sip Server = freespeech.ie
Sip User ID = your Freespeech number 07 etc etc
Authenticate ID = same as above (Sip user ID) 07**** etc
Authenticate Password = your account password
Leave all other fields as the default.

Scroll down the menus until you find:
User ID is phone number: No / Yes (select yes)
Use random port: No / Yes (select Yes)
NAT Traversal: No (even if you are NAT leave this as no)

As i have yet to find out the exact ports this network uses i have set my Grandstream to have a fixed internal IP address. I have then set up a DMZ in the router to point to this internal address the Grandstream is on. I have yet to find all the ports that this network uses so i have had to set the DMZ. If any one knows the total port range Freespeech use i would be grateful if you could post them here.

Thx Fudskie......

The ports you need to have open on Outbound Policy (towards the internet)
=========================================================================
A residential firewall is normally configured to allow any ports on Outbound.

SIP (signalling):5060 (UDP & TCP)
STUN (NAT-TRAVERSAL if you use): 3478 (UDP)
RTP (media/voice) - this is dependant, normally in the range from 5000 - 1000 (UDP). If your talking to other SIP clients then it's peer-2-peer so it's dependant on the range they use.

The ports you need to have open on Inbound Policy (from internet)
=========================================================================
These ports are the ones you configure on the phone.

This default are normally

SIP:5060 (UDP & TCP)
RTP:5000-1000 (UDP)
