I have a problem with 2 faxes connected behind an ATA 186. The CCM version is 4.1.3. When I try to send for example 2 pages to these faxes, only some piece of the pages is received and it takes a lot of time. When I see on the gateway with the command "debug isdn q931", I can see that the call try to connect several times...
Do you have already seen this kind of issue?
