Hi Experts First of all apologies for my ignorance about ss7 as i am new to it ..I provide some premium voice service to telcos, earlier i used to work with PRIs and dialogic card, asterisk fascinated me when i had a look at it..my provider says he'll provide me a ss7 link now - in dialogic world this means i need a septel card (quite expensive).. i bought a TE420P and played with it using PRIs and SIP extensions...i read that this card supports ss7 ...my questions - (please forgive me if they sound silly !) 1. Is ss7 just like a PRI cable ? or is it a V.35 like cable that acts as ss7 signalling ? do i need anything in addition to TE420P ? 2. how do i do the actual connectivity ? 3. i read chan-ss7 and libss7 provide the ss7 support on asterisk ...is libss7 (the open source one) reliable ? 4. "where do i insert" the ss7 link ? and how do i test it.. thanks in advance Sriram -------------- next part -------------- An HTML attachment was scrubbed...
