I assume VoicePulse is pure public internet SIP traffic correct? I'll be honest, everyone that I talk to has had issues using asterisk at an office site with a remote public internet SIP provider. I mean it works, but there are these intermittend outages issues. It all comes down to price. The pure public internet SIP traffic is the cheapest, but has the most stability issues. The next level up is to get a DS1 data circuit from a provider that offers SIP over that private line (i.e. MPLS). This will be much much better for overall reliability. Price wont be too bad once you get past the $400 or so for the data line. Some big providers (like XO) are starting to do this more and more now. Another option is to simply get voice lines right into the asterisk box. Going that route, the cheapest option is to get a channelized voice T1 with 24 analog ports coming of a MUX. You can then feed those lines into asterisk via a digium card, OR, use an IAD and convert it to SIP going into asterisk via TCP/IP. The analog digium card is probably the best bet. A channelized voice T1 is pretty competitive price wise, much less then a data T1. -John ---------------------------------------------------- >From : W.
