Probably should join the app_rpt mail list but,
If I understand your issue
Your issue is a matter of registration from your system.
Look in your iax.conf and see that you have a line with correct password data like this....
register = 48396:9b3e98a6aacd1@... ; This must be changed to your node number, password
; remove the leading ";"
You may need to verify your password for type error by checking it against that stored at the node data at allstarlink.org
Once that is rx and logged, your IP connection data will go into the list spread to all nodes within about 20 minutes and show in the list of connectable nodes
So, if you have verified that is correct,and still having a issue, let me know. And state the node number in question.
