Wireshark · Wireshark-dev: [Wireshark-dev] [PATCH] Avaya Display when codeset = 6

[Alfred Alinazar <aalinazar@xxxxxxxxx>]

Hi All,

Please find a little patch against revision 20149 to
epan/dissectors/packet-q931.c
The patch is to dissect unknown information element when an Avaya PBX
use codeset = 6 to send display.

The sample of avaya capture can also be found attached.
Would you like to consider it please ?
Thanks in advance.

regards,

-Alfred-
