My vote is for the Sipura as well; essentially I agree with all of Brian's points. Those boxes work well once set up correctly. And, the server and PSTN line doesn't even have to be close; PSTN line in Washington, * server in Texas and a slooooow (as in 128 kbps) DSL between them is sufficient.
There are two "issues" that I can think of: 1) as an outgoing FXO interface you do not get any call progress; the Sipura will answer the call right away and pass down the PSTN audio; it does not do busy detect or the like on outgoing calls. For incoming calls you can have * when to answer the call, if at all. Call disconnection detection and the like works quite well once tuned (which isn't always trivial). 2) Indeed there is low audio volume on *SOME* calls. In my experience it always occurs with the same callers, so it's somehow related with the other end. Personally I did not find it to be an issue (the conversation can be understood just fine) except voicemail tends to detect silence when there is none in these cases. The recorded part is actually fine, low volume but quite understandable. --Luki _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
