Hi, I'd like to add an Asterisk server to an existing setup with an Alcatel OmniPCX PBX. There are 2 ISDN BRI's coming into this PBX. Goal is: - enable the existing phones to call SIP phones - enable SIP phones to call the existing phones - route external ISDN MSN and VoIP DID numbers to either group Thanks to this forum, I found references to the Patton Smartnode 4638 and the Lancom 1724. Is either of these devices the best choice for this kind of setup, and what are the advantages of one over the other? I see that the Patton is cheaper than the Lancom, although it has an extra lifeline port. Does it have less features? Is it true that it is more difficult to configure (what about webinterface in the latest software release?)? How do they compare in voice quality, echo suppression etc... ? Vielen Dank!
