Gets or sets the maximum call transfer time.
Assembly: Microsoft.Rtc.Collaboration (in Microsoft.Rtc.Collaboration.dll)
Thrown if the maximum call transfer time set is less than 1 minute or greater than 30 minutes.
When a transferor tries to transfer a call, a rogue third party application can keep the transfer operation alive for an indefinite time. If the transferee has not sent a final notification within the maximum transfer time then the transfer operation will fail automatically and the call will be terminated. By default, the maximum transfer time is 10 minutes.
