[OpenSIPS-Users] engage_rtp_proxy()

[Max Mühlbronner]

Hi,


@Miha: Are you sure that it does not automatically set the rtpproxies 
for 200OK & ACK?

@Sasmita: According to the documentation it is not necessary to invoke 
engage_rtp_proxy() for replies as this is handled by the dialog module.


"Function must only be called for the initial INVITE and internally 
takes care of rewriting the body of 200 OKs and ACKs. "



Best Regards

Max M.
