Don Posted September 3, 2008 Report Share Posted September 3, 2008 In our operating environment we have multiple PBX instances at resorts that are nearby each other. Each building has it's own IP service via fiber optic entrance. We have a high speed microwave IP route between the buildings for backup. This allows us to route to the alternative path on a fiber failure. This works fine for video and Internet restoral. We would like to be able to be able to send calls from the PBX in one building to the other so that on a failure of that building fiber systems calls could still be completed via the link to the redundant IP entrance. Is there any way to tandem SIP calls? In other words can a call coming into a SIP trunk be routed to another SIP trunk in a tandem arrangement? This would allow us to have DID traffic sent to the backup SIP trunk and then completed on the appropriate PBX. Kevin Moroz suggested that in 3.0 using the tandeming capability that was added for MS Exchange Server calls may be a potential answer. Any help is appreciated.
