Hi, I'm looking to install/configure a 3CX system to replace an existing traditional Nortel Meridian PBX served by an ISDN30. Q1) is there anyone else out there doing connectivity to an ISDN30 for outbound calls in this forum? Q2) if the answer to the above is yes, are you in the UK? and if so - what gateway are you using and can I poach some config screen-captures from you? Q3) is the Patton Smartnode 4960 the right device for me? (it *appears* to be, but appearances can be deceptive!). I basically want VoIP inside the office and then ISDN30 for the trunk connectivity. My problem is that the 3CX help files detail how to set up a Smartnode 4638 BRI gateway, but not a 4960. Finally - I would *LOVE* this forum to include country-specific config details of at least one of each of POTS/BRI/PRI gateways available, so that I don't look like an idiot when I spec up a quote and come to install it and can't. Cheers, Mike.
