Hi to all
Since this morning one of the main trunks group keeps failing when you try to make a call sounds like occupied, when this happens i reset the trunk with the command busyout trunk 4 and release trunk 4 and the trunk function again but in a few minutes the same, the trunk goes down, y made a test trunk 4 and when the command make the test 314 send the error 2053 and result ABORT, i only want to know if the problem is of the provider or is in the PBX, i think is the service provider because another past time when this problem happened was a problem in the provider, but how can i be sure.
Thanks again in advanced !!!
