This system is brand new and has been installed for about a month now, no issues. The ComIP module works perfectly, all the PIRs and keypads etc. The only issue I cant resolve is the SMS feature on the Com2400. I have tried all the TAP providers I can find, I even signed up to OpenTAP. When I perform a test from one of the keypads, it stays on connecting SMS for about a minute, then fails, trys again for another minute and then says SMS failed, then resets the module. The log simply says "ARC 1 Test Call via Com2400 Failed". If I pick up a handset while the test takes place, I can hear it dial the number, then I hear a message from the phone provider telling me to redial the number and try again. If I dial the house phone twice, the Com2400 steps in and I can hear beeping, so it appears to be functioning properly but I am at a complete loss.
