In order to change the attribute in the SDP, you need manually to alter the
SDP (at least for 1.5.x). Tha NAT-Helper module will not do this for you.
Please see the Textops-Module on how to do this.

hello,
I use kamailio 1.5.4 with rtpproxy 1.2.1
I try to change the ptime (RTP packet size) with the Nathelper module .
to do it I call the function rtpproxy_offer with the option "z20" but the
"a=ptime:30" in SDP is not changed
any idea ?
Regards
Laurent

So, the 'z' option to force_rtp_proxy() will only request that
rtpproxy perform repacketisation using a different duration, but not
actually alter the SDP accordingly?

Correct. Maybe we could add this later, but for now, this is correct.

I see.
Well, this should probably be made clear in the documentation. I do
not think it is unreasonable for someone to think that
force_rtp_proxy("...zNN") performs necessary SDP body rewriting, since
it does this for some other flags/options to it.
I suppose it is kind of silly for me to say; I have commit privileges
for documentation, I should fix it myself. :-) Problem is I forget
how to use git, since I never do.

Hi Alex,
ok, if you send me a patch, or add it to the tracker i'll of course gladly
commit it for you. But i also must admit that i need from time to time a look
to the git cheat sheet.. ;-)
Cheers,
