Hi there I have a elastix system up and running However someetimes I got some issues with it may someone help me please. I have a Openvox A1200P with 4 FXO modules and 4 FXS, I´m located in Ecuador and only have 2 pstn lines connected to two modules in the card the others are not in use by now. All runs well when it wants but sometimes a loop call is generated between the two pstn lines and I got a message that all trunks are busy so I have to enter to FOP and close this lopp calling between the two pstn lines. When this happends is random and only generates between the pstn lines or modules not with the internal. So anyone knows how can I stop this trouble from ocurring. Thanks for the help.
