I need to create a partitioning of a Gateway Patton 4114 for outbound roule, in particular I need to uso interface 0/0 and 0/1 for a rule, 0/2 for another rule (reserved line for collegue calling) and 0/3 for fax line. With the previous versione of 3CX no problem beacuse was created many SIP account as the line present on the Patton and then I was able to applye the old trick for this problem. With v15 I have only one SIP account for the gateway and the trick is no more valid. A workaround is to use and old config file and threath the line associated to the single sip account. There is a template or a way to do this in a more clean mode?
