Description (partial)

Calls failing and Endpoint failing to respond to inbound messages in a timely manner.

Gen 1 MX Units calls are failing and the Codec is not logging / responding to Inbound SIP Message fast enough.  The packet capture from the Codec shows the message being received between 4 - 9 seconds before the same SIP message is logged by the application and the codec responds.

MX Gen 1 unit, after making several calls to a TPS will eventually start failing due to the codec not responding quickly enough to the re-invite from the TPS, the delay increases more and more as each call is made.
