I am very curius about what you have setup on your Quintum.
Specifically on the PBXTG section. Looks like you have the PBX ports “hotlined” to a I.P. address somehow.
Go to the prompt, type config, and then “print”.
If you want, mask the first octectof the I.P. addresses, post the result or send then to me to mike3799@yahoo.
I will be able to send you the text file with the corrections to make calls.
Good luck!!!!
