Hello..
Same is mine , but I have a lot of :Q931d xx.xx.xx.xx:1720 ERROR DECODING Q.931
My gateways are not h245 tunelling enabled , so somewhere in the path the buffer gets corrupted.
Here is a trace:
Original trace (last few bytes dump):
128 0 13 138 6 20 4 48 45 49 54 0 128 1 4 7 .......0-16..... 0 7 0 0 0 1 0 6 0 3 0 4 0 8 0 9 ................ 0 0 2 0 0 5 0 0 10 2 0 11 0 12 0 13 ................ 7 1 0 50 128 254 159 231 2 128 1 128 ...2........
New "buffer":
48 45 49 54 0 128 1 4 7 0 7 0 0 0 1 0 0-16............ 6 0 3 0 4 0 8 0 9 0 0 2 0 0 5 0 ................ 0 10 2 0 11 0 12 0 13 7 1 0 50 128 254 159 ............2... 231 2 128 1 128 254 159 231 2 128 1 128 ............
I'm trying to have the code altered now..
Regards Alex
