Hi,
Sometimes one of the BRI lines gets this q921 messages:
ISDN BR0/2/1 Q921: L2_EstablishDataLink: sending SABME
ISDN BR0/2/1 Q921: User TX -> RRf sapi=0 tei=123 nr=2
ISDN BR0/2/1 Q921: User TX -> SABMEp sapi=0 tei=123
ISDN BR0/2/1 Q921: User RX <- SABMEp sapi=0 tei=123
ISDN BR0/2/1 **ERROR**: L2_AdvanceVA: TX_ack_queue empty
This is already weird, but what I don't understand is the SABME message being received.
Anyone seen this, or knows what it might be?
Thanks,
JH

I see many trouble reports with that, you might try eg, 12.4(22)YB4.
