Hello everyone, I just installed and configured FreePBX connected to a GSM VOIP Trunk (mine is the Yeastar TG100, which allows me to turn the GSM mobile line via SIM card into VOIP).
I set up a call group, but I also wanted to set an external number in the call group, so that all the extensions would sound and also an external number at the same time. I saw that this would be possible by adding the external number in the group call list, followed by the #. I tried, but unfortunately only the internal phones (extensions) ring and the external number is not called. I doubted that with the GSM gateway it is not possible to make and receive calls at the same time, so I tried while I was on call on an extension number to dial an external number and in fact the call fails if I am already on call. At this point my question is: is there anything I can do to be able to forward the call outside via the GSM gateway? If instead, as I think, it is not possible I thought of setting up a second trunk with a voip provider so as to use that line for forwarding calls destined for the GSM gateway trunk, but I have no idea how it is possible to configure it this way… Can you tell me the best way?
I look forward to an answer. Thank you!
