I have a ssabel installed with 2 SIP trunks for 2 HT503, and on the output route I put it to exit HT1 and if it was busy going out on HT2, but when I make a call, the issabel goes out on HT1 and it works, when I'm on HT1 and I try to make another call, that does not make the call because it says that all the lines are busy, it should go to HT2 but it does not obey. Does anyone have a way for this to work, any parameters I put on the console maybe?
on elastix I edited the file extensions_additionals.conf and added the line exten => s-CHANUNAVAIL, 1, Goto (continue, 1)
