We have 2 main offices, each using their own callmanager installation. site A uses 6.1.4, site B uses 6.1.2. We have an ICT built and regions look good with device pools associated with each and look to have appropriate codecs assigned to each region.
When we call across the WAN to site B, the call is completed, but when we attempt to conference in an external PSTN call from site A, the call at site B is dropped after 2 short beeps.
any ideas on where i can look?
sidenote: not sure if this uses conference bridges or not, but the default conference bridge that was built with our subscriber server, does not show registered. the CFB to our publisher does, all the phones in site A are registered to the subcriber.
