Our RTPproxy bandwidth is very limited. We will only allow about 5 of our mobile users to utilize the proxy. Essentially we use our SER for our own internal communication world wide. If we do not restrict it's use I know we will have some IT managers that will not bother to setup port forwarding etc as the Phones will work with out it.
The solution Andres listed below seems VERY suitable for our needs. I plan to look at that approach instead. However I could use some help with that. Using serctl I see show, grant & revoke How do you create a new group ?
Edit serctl file so that you have a line like this: ACL_GROUPS="local ld int voicemail free-pstn prepaid rtp_proxy"

So you have to configure each user if he is allowed to use rtpproxy or not? And what is if the user is mobile - some times behind NAT, some times not?

For a REGISTER will the below be true if the UA that is registering

a 5 in the 4th digit
ie 1115999 true 1114999 false
if (uri=~"[0-9][0-9][0-9]5") I saw some where in the docs that "User name is optional (it is for example never included in REGISTER requests)"

So I take you are simply trying to centrally manage whether a user is
to
be foced through the RTPProxy or not. Seems your are trying to do
this
with a numbering scheme which is quite cumbersom. We are testing a
more
flexible approach based on acl groups. We simply defined a new acl group called "rtp_proxy". On a request like REGISTER or INVITE, Ser will check if either the "From" or "To" usernames belong to the group and apply the RTPProxy. Something like:
# Check if caller is on the rtp_proxy group if (is_user_in("From", "rtp_proxy")) { setflag(2); force_rport(); fix_nated_contact(); exec_msg("echo `date` - Caller is in rtp_proxy group -From: $SIP_HF_FROM To: $SIP_HF_TO Contact: $SIP_HF_CONTACT >> /var/log/ser/rtp_proxy.log"); };
# Check if called user is on the rtp_proxy group if ((is_user_in("To", "rtp_proxy")) & !(isflagset(2)) { setflag(2); force_rport(); fix_nated_contact(); exec_msg("echo `date` - Called User is in rtp_proxygroup
- From: $SIP_HF_FROM To: $SIP_HF_TO Contact: $SIP_HF_CONTACT >>
/var/log/ser/rtp_proxy.log"); }; . . . if (method=="INVITE") { if (isflagset(2)) { # rtp_proxy group ? force_rtp_proxy();
}; # /* set up reply processing */ t_on_reply("1"); };
