[Serusers] RTPProxy issues

[Ezequiel Colombo]

Hi, i am testing RTPProxy with SER-0.8.14-4 and have 2 questions.

First, for what reason nathelper module insert "a=nortpproxy:yes" to SDP
when use force_rtp_proxy() ???
This cause UACs like Azatel and Cisco IOS warning about this unknown
attribute.

And the other, i see in my ser logs a message like:
"ERROR: send_rtpp_command: can't read reply from a RTP proxy"
when use unforce_rtp_proxy()

Thanks
