Your exchange sends Q.931 messages which are not known and/or ignored by
i4b. They are:
	0x6b - this message is not defined in Q.931
	0x6c - REGISTER ACK (outdated/old, not defined in Q.931 3/93)
	0x6e - NOTIFY

Either the exchange sends some proprietary messages or conforms to a very
old and no longer valid version of Q.931.

T202 is the Q.921 timer which is used to timeout TEI id requests. The above
message means that your exchange did not respond for 3 times (N202 = 3) to
a TEI id request from i4b within 3 times T202=2 seconds.
