Disclaimer: I work for a company that sells commercial Asterisk-based PBX-es. I'll just note that there are companies and companies that give you Asterisk as a commercial and supported product. The tradeoff here is that you are then (depending on the terms of the support contract) less free to tweak the system. From your description this seems like an important feature. (I am not familiar enough with FreeSwitch or any other software and can't comment on them) > > We have did some searching of Asterisk, here are my questions: > > 1. Does the last Asterisk using PJSIP stack ? Asterisk uses PJSIP as of version 12. It was added alongside the internal Asterisk SIP "stack" (chan_sip.c: a file that exceeds 1MB and people don't enjoy changing). In Asterisk 13 it became the default. > 2. Does there has the comparison of PJSIP and reSIProcate, sofia(using by > FreeSwicth) ? I believe that sofia's independent development is rather lacking at the moemnt. At the time the FreeSwitch developers chose it it was the best choise. But when it was time for the Asterisk developers to replace chan_sip with a saner SIP stack they preffered reSIProcate (even though it was C++ and not C as Asterisk it) and PJSIP (even though it required patching it to allow dynamic linking) over sofia. Because at least at the time the sofia stack was lacking development. See https://wiki.asterisk.org/wiki/display/AST/SIP+Stack+Research > 3. Is it easy to compile and setup Asterisk? Yes, basically. But what do you want to do with it? Asterisk (and also FreeSwitch, as I understand it) is not a PBX. It is a toolkit with which you can build a PBX. For instance, FreePBX is a PBX based on Asterisk. But do you really need a PBX? Or do you need a more generic telephony server? > 4. Which Asterisk version is recommended? That depends on the timing of your product. In Asterisk odd versions are LTS (maintained and supported for a longer time frame). The current LTS is 13 but 14 has also been released. Specifically PJSIP is one of the features that has been maturing. If you want a PBX right now, go for 13. If you aim for a product to be released a year from now, use current git master and wait for it to become 15. > And does Asterisk support Windows ? Asterisk does not run on Windows. -- Tzafrir Cohen +972-50-7952406 mailto:tzafrir.cohen@xxxxxxxxxx http://www.xorcom.com _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip@xxxxxxxxxxxxxxx http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org
