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

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 :-)

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
