Denis, if you are connecting to rtpproxy via an UDP connector, simply use
ngrep (on the configured port). If using a unixsock connector, switch to a
UDP one (rtpproxy_sock = udp:localhost:8899 and do a similar change in the
rtpproxy command line).

Hi Denis,

could you make a capture to see the comunication between opensips and
rtproxy ?

Hello Bogdan

 

I am very sorry, last time I gave wrong information about the problem. Only
with "r" flag there is no fax stream through rtpproxy (last email I said
that everything is OK, but I made wrong test).

Here http://files.mail.ru/XF4J0L 

Is tcpdump of unsuccessful call.

Hello Bogdan

 

I applied "r" and "a" flags and problem with fax disappeared, but I got
another problem. After I applied "ra" clients behind nat cannot hear caller
or callee (never mind who makes call).

Rtpproxy is working, i.e. it changes SDP body of INVITE and replies, but
there is no rtp stream.

Hi,

According to your trace the RTPproxy is properly inserted during the
re-INVITE. Try to put the "r" and "a" flags when using RTPproxy from script.

Hello Bogdan

 

Thank you for answering. 

My case is 2).

First I have audio stream which is replaced later by another fax stream.

Here http://files.mail.ru/8BYVCQ

is a tcpdump of unsuccessful call where you can see that rtpproxy doesn`t
proxy fax stream.

Rtpproxy (as an Opensips) is located on 213.170.100.150

Hi,

You may have 2 cases, not sure which is yours:

1) the 2 media sessions are in parallel in the same calls (you can have 2
-or more- RTP streams in the same SIP session). In this case, RTPproxy will
take care automatically of each RTP stream)

2) you have first one audio stream which is replaced by another FAX stream,
via a re-INVITE - in this case, if you the normal offer / answer for
RTPproxy also for the re-INVITE, it should be ok.

Hello

 

There is one question about rtpproxy working.

If some UA using 2 different UDP ports for sending RTP and t38 fax packets
during one call session, whether rtpproxy is working (proxy both UDP
streams) in such case? 

 

Thank you for any help
