THREE PACKET TYPES FIGURED OUT!

Browse Source 
0x61, 0x62 and 0x63 have been mostly decoded. Still don’t know what all
of the pieces do, but know what they’re for finally!

This will mean big things for log.py as I figure out the details.

The following sections of this document will include various packet types. This is a list of currently known types and their meanings. Note: The names are arbitrarily chosen with the intention of being descriptive, and each is defined by what they've been "observed" to do in the wild.
CALL_CONFIRMATION = 0x05 Confirmation FROM the recipient of a confirmed call.
CALL_CTL_1 = 0x61 |
CALL_CTL_2 = 0x62 | Call control messages, exact use unknown
CALL_CTL_3 = 0x63 |
CALL_MON_ORIGIN = 0x61 Sent to Repeater Call Monitor Peers from repeater originating a call
CALL_MON_RPT = 0x62 Sent to Repeater Call Monitor Peers from all repeaters repeating a call
CALL_MON_NACK = 0x63 Sent to Repeater Call Monitor Peers from repeaters that cannot transmit a call (ie. ID in progress)
XCMP_XNL = 0x70 Control protocol messages
GROUP_VOICE = 0x80 This is a group voice call
PVT_VOICE = 0x81 This is a private voice call
