Release notes: AMTMitelCRE 1.6.3.25

[Hilton Williams]

• Fixed bug in the jitter buffer - previous timestamp was not being cleared (this causes new RTP streams to be checked against the timestamp of the previous stream) - this only affects multiple SSRC streams (rare on the Mitel).
• Fixed bug where last packet of each RTP stream was not being processed - see 1.6.3.21.
• Reference numbers counter portion is now shorter (6 characters instead of 8), as discussed with Johan. This allows up to 16,777,216 recordings in 6 hexadecimal characters. If they do more than that, it will simply expand to 7 characters.
• Disabled on-startup processing of previously recorded RTP files.
