[asterisk-users] Asterisk with SRTP and SIP with TLS
Dear all, I want to know if anybody has implented an Asterisk server (1.4 or 1.6) with SRTP and SIP with TLS, in order to encrypt both signaling and voice packets. Is it possible ?? And in the affirmative case, does encryption increase the delay and so the voice quality becomes wrong ??? Thanks a lot. Alejandro
Does anyone know of a phone product that: 1. Would plug into a DHCP IP port and get an address. (i.e. Cable modem) 2. Has a second Ethernet port and would bridge that address (perhaps pseudo DHCP so that following computer would be unaware of subterfuge.) 3. Would be a SIP phone doing the "usual things", "stealing ports" as needed from the IP and forwarding other traffic to the following computer. Perhaps a phone with a built in router would accomplish the same thing, and allow multiple following computers. Anyone know of any such product. The intent is to have a decent phone that when plugged in between a cable modem and a computer would provide VOIP without a bunch of boxes and cables. Cary Fitch

Great, how do you relate firmware rev to this feature, and I wonder if they do it with a Budge Tone 200?

Or will that deliver only ONE IP at a time? Chris -------------- next part -------------- An HTML attachment was scrubbed...

They are great little ATA/Routers for just a few bucks! I still use them regularly as either just ATAs on conference phones (POTS Polycoms and for the router piece since there i no NAT to worry about. It makes shipping a unit to a non-technical customer a breeze. -- Thanks, Steve Totaro +18887771888 (Toll Free) +12409381212 (Cell) +12024369784 (Skype)
