Wireshark-dev: Re: [Wireshark-dev] IMS-Information AVP not correctly parsed

Change the type-name attribute to "Time".

Someone (maybe me, but not for a few days at best) needs to
rationalise these duplicated AVPs (between dictionary.xml and
chargecontrol.xml).  Anders?

If you get it dissecting nicely there, please do send patches to this list!

cristian: hi martin! thanks. I had a look in the dictionary.xml at the
IMS-Information avp and its component avps definitions. specifically at
timestamps:

<avp name="SIP-Request-Timestamp" code="834" mandatory="must"
may-encrypt="no" protected="mustnot" vendor-bit="mustnot" vendor-id="TGPP"
>$
<type type-name="UTF8String"/>$
</avp>$
<avp name="SIP-Response-Timestamp" code="835" mandatory="must"
may-encrypt="no" protected="mustnot" vendor-bit="mustnot" vendor-id="TGPP"
>$
<type type-name="UTF8String"/>$
</avp>$

I think they are supposed to be of Time type. (type is def. in diameter
base protocol). here are the relevant defs from 3gpp specs (32.299):

7.2.112	SIP-Request-Timestamp AVP
The SIP-Request-Timestamp AVP (AVP code 834) is of type Time and holds the
time in UTC format of the SIP request (e.g. Invite, Update).
7.2.113	SIP-Response-Timestamp AVP
The SIP-Response-Timestamp AVP (AVP code 835) is of type Time and holds the
time in UTC format of the response to the SIP request (e.g. 200 OK).

bye now!
