[OpenSIPS-Devel] [opensips] rtpproxy: bogus command modifier (#195)

[Ovidiu Sas]

There is a bogus character 0x01 sent after U command when calling rtpproxy_engage("").
If calling rtpproxy_engage(), everything seems to be normal (please note the missing double quote).

rtpproxy output log:
<code>
DBUG:get_command: received command "6197_17 U#001c0,107,8,101 LYTy2eZwa8DCiwQ.XwUB5RAyuvXqxK0T XXX.XX.XXX.XXX 4010 K2HuCGCbGY-3pdBhz9EUBt.XAJH0yblY;1"
ERR:handle_command: unknown command modifier `#001'
</code>

Here's a tcpdump of the exchange messaging between opensips and rtpproxy:
