[Kamailio-Users] Quick RTPproxy question

Hey, thanks for both replies from Daniel and Klaus.

Klaus, will this work on kamailio 1.5.3 the same way?
Daniel, sorry I misstyped. The first flags should be ocfaei and the second
ones ocfaie.

What I meant with the question is:
I receive an invite from public IP; I call force_rtp_proxy("ocfaei");
Then I receive the reply (lets say 183 or 200) and I call
force_rtp_proxy("ocfaie");

Is this right?

Thanks in advance,
Uriel
