Yealink T19 Crashing 3CX

[jasonhayes]

Does anyone use the Yealink T19's? We have three, if we have them in a queue, after a few hours/calls, 3CX crashes, all phones T20's, T22's hang for a minutes or a few seconds. We have removed the T19's from the Queue and for the last five days we have had no crashes. We didn't have crashes on 3CX after we upgraded to V12, then a few weeks later when we recieved the T19's from our supplier we installed them and then 3CX started crashing. The T19's are on firware: 31.71.0.35 (which is Supported by 3CX Phone System)
