I'm getting in a muddle! I have set up the following trunks: mobile - making use of an SPA3102 & a GSM gateway ZAP - 4 channels of BRI I can make/receive calls on any of the 5 lines. I am wanting to force the first 07 call over the mobile trunk. Any other simultaneous 07 calls should then go out via the ISDN. In addition, any calls that do not begin 07, should always go over the ISDN. I have two outbound routes as follows: Mobile with 907. being the Dial Pattern Trunk sequence being mobile then Zap In the mobile trunk, the dial rule is 9|. which strips the 9 and dials the rest of the mobile number over the GSM & it works fine. ISND2e with 9|. being the Dial Pattern Trunk sequence being just Zap In the ZAP trunk, the dial rules are . and 9|. So, any calls starting 07 go out correctly on the GSM gateway. Any other calls go out correctly on the ISDN........BUT.......if a second simultaneous call to a mobile is made, I get engaged. It seems, even though I have set the maximum channels to 1 in the mobile trunk, FreePBX trys sending the 2nd 07 number over (the already) in use trunk. Either that, or I've got the outbound routes' Dial Patterns &/or trunk Dial Rules wrong.... Unfortunately, I don't have access to the CLI, & I'm remote from the machine & just have web access to FreePBX... Anyone able to shed any light on my predicament?
