HI, I have installed a Portech MV372 GSM gateway on our 3CX system v.10 using the official 3CX installation guide. And everything seems to be working fine. I can ring both in and out. But the problems start when i want to use rules to guide the traffic around. I made the following simple rules and placed them ontop of all other rules: (the actual phonenumbers are replaced) Calls to number (prefix): 98123456 Route: GSM 1 Strip: 0 Calls to number (prefix): 98654321 Route: GSM 2 Strip: 0 Calls to numbers with a lenth of: 8-14 Route: SIP provider Strip: 0 I my head this is how this should work: If i call 98123456 from any extension it should use GSM 1 as route, and it does. But if GSM 1 is busy and i call 98123456 from another extension i just get a busy tone. Instead i was expecting it to route the call to my SIP provider instead since there is an according rule for the purpose below. The same is the case when i 98654321 and GSM 2 is busy it doesn't route the call to the SIP provider instead. If i then instead make only one rule and set the following Calls to number with a length of 8-14 Route 1: GSM 1 Route 2: GSM 2 Route 3: SIP provider Strip: 0 in all cases Then it seems to work fine. Then it will automatically start from the top untill it reaches an available route. But unfortunately we have a rather complex pattern for outbound calls so this is not an option. Someone sugested that it was a license problem but i have tried to re-activate the license with no result. Any suggestions? I'm in quite a predicament since we have to install several of the gateways very soon.
