Hello I am hoping you experts can help me out here please, We have an IP Office 9.1.6 500v2 with 3 expansion modules, 2 analog 30 and 1 16 analog module, not able to fax any outbound fax numbers, inbound is fine. If the analog line is connected directly to fax machines (3 in all and yes all have the same issue) we are able to fax with no issues at all, the problem is when they go through the phone system it is only out pulsing 5 digits in lieu of 7 digits, the funny thing is that if I use the handset from the 3 fax machines I can call any number. But as soon as we try to fax any 7 digit local fax number we get a error message that says the number you called can not be dialed please check the number message. We have verified this through system status, we have tried everything, all analog modules are on the same software release as the control unit, we do have a user short code that tells the fax to use the same analog lines to fax out on. We had to do this because we could not fax across the scn to go out the PRI at the main site. We also have this same set up at the 2 other schools and all work fine except for this junior high school site, I was hoping that you guys could help me out here as I am at my wits end, thank you all for taking the time to read this.
