We have a client that is considering switching from Vonage to Thirdlane/3CX.
They HEAVILY rely on the mobile client and we lost this customer about 18 months ago because of the lack of backwards compatibility of the mobile client with older server versions.
As was discussed in this thread, https://www.thirdlane.com/forum/newbie-with-thirdlane, this is such a vital "feature".
Essentially, they got tired of waking up one morning or some random point in the day and their mobile phone Thirdlane client updated and they suddenly could no longer receive calls until the server could be updated. This amounted to a loss of ~200 extensions to Vonage.
They are willing to give us another try because Vonage obviously has a much higher price point, but not losing their mobile client connections to the phone server due to unknown and unplanned updates is an absolute hard requirement and something that even 3CX struggles with in some releases.
I could potentially bring these people back, but I would need to know if this is going to be implemented moving forward and when to set the proper expectations with the client so that can keep their trust in us.
