[Serusers] Invoking force_rtp_proxy() after fix_nated_sdp() error

[Tomasz Zieleniewski]

Hi,

Invoking force_rtp_proxy() after fix_nated_sdp() causes error
that in the connection filed one ip address apears after second
(previous one is not removed)

v=0.
o=- 3 2 IN IP4 192.168.1.3.
s=CounterPath X-Lite 3.0.
c=IN IP4 82.210.160.59192.168.129.74.
t=0 0.
m=audio 35036 RTP/AVP 107 119 100 106 0 105 98 8 101.
a=fmtp:101 0-15.
a=rtpmap:107 BV32/16000.
a=rtpmap:119 BV32-FEC/16000.
a=rtpmap:100 SPEEX/16000.
a=rtpmap:106 SPEEX-FEC/16000.
a=rtpmap:105 SPEEX-FEC/8000.
a=rtpmap:98 iLBC/8000.
a=rtpmap:101 telephone-event/8000.
a=sendrecv.
a=direction:active.
a=oldmediaip:192.168.1.3.
a=nortpproxy:yes.

in the example above
fix_nated_sdp put the 82.210.160.59 address
and force_rtp_proxy instead of replacing the 82.210.160.59
appended it at the end of the line

Cheers
