H323 Annex E over UDP and TPKT header

[Sasha Ruditsky]

Hi Vivek

The only function of TPKT is to define message boundaries.
Annex E has own mechanisms to do this.
So basically I think that should be no TPKT header in the Q.931 messages
when used with Annex E.

Hello,
I wanted to poll the H323 community regarding the use of TPKT header with
H225 message while using AnnexE transport capability. AnnexE makes the UDP a
reliable signaling channel. H.323 spec talks of using TPKT header with
reliable signaling channel.

What is your interpretation of H323/AnnexE regarding the TPKT header? Does
the TPKT header  have a function in this case?


thanks,
