At the risk of being redundant, VoIP and Alarm is known not to mix well. Some of the tones used by an alarm system do not behave in the same way as conventional DTMF. This will vary greatly based on the actual alarm format used (and there are at least thirty different formats.) I don't know the specifics, and there are few who do due to the proprietary nature of the industry. While I've never used the alarmreceiver application, I have used some of the best industry equipment available. Again, we just can't get VoIP to be reliable enough for alarm transmission. I really, really wish we could.
I blame compression, as we have the exact same kinds of problems with digital cell service... Now, rather than just being a nay-sayer, let me refer you to the Bosch C900V2 device. It takes a signal from just about any panel and converts it into IP to be received by a Bosch receiver. It's a good fit for nearly everyone. Also, there's a good chance your alarm panel has an IP module. Call your installer and ask them what your options are. If they won't help you, go to www.ul.com (in the US at least) and start looking up listed Central Stations in your area. Call them and ask if they support your panel over IP. You can probably get monitoring from a UL-listed Central Station for a price you'll be willing to pay. There's a lot of competition out there. This money gets you 24-hour, redundant coverage, which is in my opinion worth it's weight in gold. If you need any alarm industry guidance, please feel free to contact me off-list. I could probably even refer you to a good CS if you'd like. Please don't misunderstand, I don't mean to detract from the alarmreciever application. There are some really interesting applications to be had, e.g.: 1) Your alarm panel calls asterisk, which notes the alarm zone and connects your cell phone to the nearest intercom device. 2) 'Who are you, and what do you want?' 3) You could then have the capability to cancel the alarm before the panel dials your central station. This would save on false alarm calls and could speed up response greatly. Also, if you failed to answer your cell, the CS would dispatch as normal.

Which ATA can I use? I tried to set up it with Linksys PAP-2 but with no luck. Maybe I did something wrong with alarmreceiver.conf (I tried diverse settings, but nothing worked). Sometimes alarmreceiver is able to get some events but sometimes not. I think Linksys PAP-2 has a problem with recognizing digits in appropriate way.
