+ <p>The error counter <em>medGwyGatewayNumErrors</em> did not work.
+ This counter is incremented by the megaco application
+ when decode of a message fails. Due to the
+ construction of the decoders, nothing beyond the
+ error reason (in the text case, basically an
+ unintelligible list of tokens) is returned. E.g. not
+ the Mid needed to be able to deduce which MG
+ (conn-handle), this message came from. This resulted
+ in an increment of the "global" <em>medGwyGatewayNumErrors</em>
+ counter instead of the connection specific.
+ This has been fixed. In the text case by adding a mini
+ decoder, that basically only decodes the message as
+ far as the Mid (if the error is in or before the Mid,
+ then this decoder also fails).</p>

+ removed those record which had the state field
+ set to <em>wait_for_ack</em>, and not <em>aborted</em>!
+ If the state had been set to <em>aborted</em> and not
+ yet been removed (which normally happens when
+ the reply_timer times out) when the disconnect
+ and cancel functions where called, those records
+ would never be removed. This means that if eventually
