Hello, We are about to attempt a provisional upgrade to the new 3CX based Elastix 5.0 on our PBX. We currently have a Sangoma A200 card installed and previously had Elastix 4.0. All phones are the Yealink T42G Is there any specific reason as to why Sangoma is no longer supported? Is it a compatibility or reliability concern or is it because it's old tech? If we did manage to get it to work with the 3CX build, would there be any point in this? We'd just like to know if there are some issues here. We are basically summing up whether to try and make the card work, or ditch it altogether and go for something that's supported, either a Patton or Welltech - a recommendation on brand would be appreciated, we're hooking up one BT PSTN line to it (second line being added in a few months). Any input would be greatly appreciated! Thanks.
