Hi,
Definity PBX uses, AFAIK, uses proprietary control on top of standard H.225 elements between the PBX and its terminals. Therefore, NonStandard element, I guess, should provide this information, but without information about its format, you can't probably find these fields.

Subject: [Ethereal-users] Q931 NonStandardControl

I took a capture of ip packets travelling between an Avaya Definity PBX and some of its IP phones.
I tried to get information from the Q931 messages about the calling and called party but I found no such infromation are presented by the Ethereal view of captured packets.
But I saw some field called NonStandardControl that has a stream of octets that is dumped to the view as-is without parsing.
Does anybody know if this field contains this information (calling and called party)? If yes, does anybody knows a resource or any idea that helps dissecting this octet stream? Will this be supported soon on ethereal?
Please advice.
