As they say, "Your Mileage May Vary" You have gone with a pre-built asterisk based solution rather than rolling your own with 'plain' asterisk system. So without knowing your particular environment, it's obviously difficult to comment. By the sound of it, your experience of asterisk has been based on one particular integrator's build of it. One or two versions of asterisk out there were lemons and were best avoided. And then there are some modules which are less stable than others. I have found that most of the core asterisk stuff to be reasonably stable and well behaved, but there are a few modules that either have problems, or have had problems in the past, which have now been fixed. chan_agent was a good example of something that worked on a small scale but certain bits of it were just broken. Other problems may be down to operating system, memory, hardware or driver issues. Here, I am using exclusively SIP devices, SIP media gateways (rather than PC hardware) with asterisk voicemail module and seems pretty stable. (We had to reboot the box 9 weeks ago for a kernel security update.) pink*CLI> show uptime System uptime: 9 weeks, 4 days, 23 hours, 44 minutes, 22 seconds We have about 77 SIP devices and these are a mixture of hard and soft phones, with four media gateways. Spread over 9 sites. There are a few ongoing intermittent issues, but haven't had any spontaneous crashes so far. > 4) If NOT, and if my expectations are that a system SHOULD just > run and run without any problems.

You could look at OpenSER but I'm not convinced you'd find that an easy thing to work with, when you describe what you want to achieve. SipX was also pretty good, but these are SIP only servers rather than asterisk's multi-protocol ability (You also have to provide SIP media gateways rather than talk directly to a card in the back of the machine) http://www.sipfoundry.org/sipX SIPx is the open source release of Pingtel's SIPEchange product, which I also evaluated. it seemed like a pretty good 'set and forget' solution, and they are also now selling an integrated SIPx appliance: http://www.patton.com/products/pe_products.asp?category=348&tab=fb&; Which we looked at and was pretty good. Up to 30 users and included automatic handset provisioning, nice GUI for setting things up etc. This is great where you have an environment where running a server is not possible. (our asterisk server is hosted in a nice data air conditioned centre with redundant disks, power, UPS, network.. everything, but no everybody can run an environment for ultra reliable servers, so an "Asterisk Appliance" might be a way forward and requires no server housing capability and very little knowledge of the operating system etc. It is very difficult to stop thinking 'old PBX', and start thinking "What is it we're trying to achieve?" If what you want is a PBX, go and buy one. It was a tricky journey from the old PBX system to asterisk VoIP, as there were certain expectations of the old system, and maintaining lots of functionality with the new handsets/asterisk. The system that replaced our PBX doesn't have anything like as many call features as the old PBX did, but then again, most of these features were almost never used. But what we did gain was much more flexibility, choice of handsets/clients, connection to various VoIP networks, the possibility of remote workers, redundancy in the new system, and integration possibilities with existing systems that were completely impossible on the old PBX system. (Or were only possible for lots of money!) Handsets are finally evolving now, trying to put in features that were present on old PBXs with 'traditional' paradigms like key and lamps etc, which users want on VoIP systems, but I believe that will ultimately lead to more proprietary systems and will ultimately fail in favour of Soft Phones, which are much better able to add new features rather than be constrained by a physical handset with buttons and memory limitations etc. In my experience, you can buy a very expensive handset or a reasonably priced soft phone that can do exactly the same features. People are reluctant to give up their physical handsets on desks just yet though. There is something to be said about keeping things simple. We decided not to go for the option of putting, say, BRI cards in the back of asterisk server and using it as a media gateway, but use separate off-the-shelf media gateway boxes to do this instead, so from the asterisk server, everything is SIP, and the media gateways are doing the awkward ISDN/Analogue <-> IP conversion. That way, any SIP server (including Asterisk) can interact with these gateways. Reading this list, some of the PCI cards and drivers are better/more stable than others. The benefit you get with Asterisk/VoIP is that you are not locked in to one particular vendor, architecture or approach, and can be very cost effective for the equivalent commercial products you would have to buy to get the same functionality in the traditional PBX world. The trade-off having an open system and flexibility, is that there are so many possible configurations/handsets etc. that it can be a challenge to get it all working. If you want somebody to have done all the work for you and not to have to worry about it, then maybe go for a packaged, proprietary solution. If lock-in is not an issue for you, then you could just buy a lucent PBX system or Cisco call manager, for example. Another approach might be to go for a managed VoIP service provider, and just connect your handsets to their service rather than run your own servers. this way, you get the benefit of VoIP without having to run your own VoIP service. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
