Hello,
I need the destination IP of the user of the first INVITE message (user ->
ser)... but dst_ip == xxx.xxx.xxx.xxx gives me the IP of ser.
The problem is that I only want to force the rtp_proxy if the users are
behind a Port restricted cone NAT (the scr-ips of them are known)
Here is my code:
# Force rtpproxy for users that are behind a Port Restricted Cone NAT
if ((src_ip == xxx.xxx.xxx.xxx | dst_ip == xxx.xxx.xxx.xxx) &&
!(uri=~"sip:[0-9]{9,30}@.*")) {
fix_nated_contact(); # Rewrite contact with source IP of signalling
force_rport(); # Add rport parameter to topmost Via
setflag(6);
}
Has anyone an idea how I can get the IP of the user? For example in the
location database?
Thanks!
Sebastian

If I understand your problem correctly you want this IP address?
user ----> ser -----> user
^^^^
dst_ip
Just an idea: you may try to write the the ruri/domain into an AVP using
avpops (after lookup("location")). Then try using avp_check, and report
if this works :-)

Hi,
I tried it with the following parameters:
# ------------- avp parameters
modparam("avpops", "avp_url",
"mysql://ser:heslo@localhost/ser")
modparam("avpops", "avp_table", "location")
modparam("avpops", "username_column", "username")
modparam("avpops", "domain_column", "domain")
modparam("avpops", "value_column", "contact")
and then
# Force rtpproxy for users that are behind a Port Restricted Cone NAT
if ((src_ip == xxx.xxx.xxx.xxx |
avp_check("contact","re/sip:.*@xxx.xxx.xxx.xxx/g")) &&
!(uri=~"sip:[0-9]{7,30}@.*")) {
fix_nated_contact(); # Rewrite contact with source IP of signalling
force_rport(); # Add rport parameter to topmost Via
setflag(6);
log(1, "Call with proxy...\n");
}
I didn't find many examples of avp_check :-(
Thanks
Sebastian

Hello,
Here my report ;-)
I used the following code:
# ------------- avp parameters
modparam("avpops", "avp_url",
"mysql://ser:heslo@localhost/ser")
modparam("avpops", "avp_table", "location")
modparam("avpops", "username_column", "username")
modparam("avpops", "domain_column", "domain")
modparam("avpops", "value_column", "contact")
and then...
# Force rtpproxy for users that are behind a Port Restricted Cone NAT (eg.
for us: IP=xxx.xxx.xxx.xxx)
avp_write("$ruri/domain","s:contact");
if (src_ip == xxx.xxx.xxx.xxx |
avp_check("s:contact","eq/xxx.xxx.xxx.xxx/g")) {
fix_nated_contact(); # Rewrite contact with source IP of signalling
force_rport(); # Add rport parameter to topmost Via
setflag(6);
log(1, "Call to Port Restricted Cone NAT...\n");
}
...and it works!
Thanks for your help!!
Sebastian
