[Serusers] Change SDP

[Benito Caracuel]

Hello All,


Basic Concept:

I have to change  the Path MSRP into SDP field in an INVITE and relay the new INVITE.

SDP EXAMPLE:

v=0
o=686873200 3372497915 3372497916 IN IP4 80.27.211.205
s=SipSession
c=IN IP4 80.27.211.205
t=0 0
m=message 49152 TCP/MSRP *
a=direction:active
a=accept-types:text/plain
a=path:msrp://80.27.211.205:49152/63331682315468750;tcp

When I receive the SDP, I have to change "msrp://80.27.211.205:49152", so  I execute an script and I obtain the new SDP into file.txt.

Now, I need to replace the old msrp path by the new sdp path, which is into file.txt

In my ser.cfg:

if (method=="INVITE")
{	
	exec_msg("printenv SRCIP > /tmp/invite.txt; cat >> /tmp/invite.txt; /bin/bash /usr/local/ser_snapshot/sbin/controlador");
        #I have the new SDP in /tmp/test.txt
        exec_msg("set `cat /tmp/test.txt`; %var = $1"); 
        #I have the new SDP in $var
	replace_all("msrp:\/\/[0-9\.:]{2,20}","%$var");
        # I don't know why $var = null!!!!  I need that $var = cat /tmp/test.txt but i don't know how to do this!!!!!
        t_relay();
	break;	
};




Please help me, 

Thank you very much.
Ben.
