the issue with your solution is that one of the extensions will be only receiving not sending.    because sending a fax is done by the printer, therefore, it will not work! ... View more

it is CUCM and yes I like this idea but would it work on sending and receiving from the same number.   if 1111 sends a fax it will send on behave of 2222 or it will send on its number?           ... View more

The reason is we want to use different two numbers for the fax (ATA 190) one device and not having two printers!   Yes, it does have two RJ11 but one has a sign of fax and another for Telephone.   By the way, it is HP Printer that has fax built-in model MFP 281fdw.            ... View more

I went to Line DN configuration and Changed the external mask number to DID number (main). Usually when I do that to DID number on the phone screen above the Line DN I can see the masked number but when I do it to the internal number it does not change anything, When I call external number (cell phone) using internal given CSS permission to call Mobile. I cannot hear anything for maybe 30 seconds then I get busy sound the call is dropped.    I will try to debug and provide it here.       ... View more

Unfortunately, it did not help or even change anything. Now I am just even trying to forward all calls to cell phone it is not even working! from DID number i can only forward to an internal number. ... View more

In fact, now I have another problem instead of using Mobile Connect I would say I just use Forward all soft key to a cell phone but either that I am able to forward calls internally but not external (cell phone). When I forward the call the calls go directly to CUC because that's how we integrated our system. on the other hand, I tried to make system call handler and transfer rule making CUC make a call to cell phone but that did not work either. ...
