[Sip] rsvp or manyfolks in 3gpp

[jh@lohi.eng.song.fi]

xin,

from your message i get an impression that rsvp is not mandatory in 3gpp
terminals:

> I am familiar with the 3GPP SIP architecture, our terminals don't use
> RSVP, ...

last fall i wrote on the sip mailing list:

to which Miguel Garcia from ericsson replied:

i'm now a bit buzzled here?  is it so that an e-2-e reservation
according to manyfolks is mandatory in 3gpp terminals, but the
reservation protocol doesn't need to be rsvp?  if so, can each handset
vendor invent their own or what?
