Hello everyone,
sorry for some inaccuracies, but this is my first post.
I connected a Sangoma Vega 50 gateway (8 FXS + 2 FXO) to my FreePBX server.
I configured FXS interfaces as extensions and a FXO interface to a SIP trunk.
I created a ringgroup which include the FXS extensions and normal extension (IP Phone).
If I use 3 or more FXS, when I call from an internal number after the first ring the call drops (I get the message “canceled received”). If instead I call from an external number (from trunks) the ringgroup works correctly.
If in the ringgroup there are 1 o 2 FXS extension, it always works well.
What could be the problem?
Thanks,
CR
