Thanks, that is what I thought as well after reading the module
documentation.
I'm still looking for ways to solve this so any pointers are much
appreciated.
Currently I have the following at the end of the main route:
if (avp_db_query("SELECT ob_proxy FROM subscriber WHERE username =
'$rU'",
"$avp(s:ob_proxy)")) {
xlog("L_INFO", "SIP Request: method [$rm] from [$fu] to [$tu]
after avp [$avp(s:ob_proxy)]\n");
avp_printf("$du", "sip:$avp(s:ob_proxy):5060");
};
This sets the destination URI to be the outbound proxy that the user is
provisioned with. I would prefer an alternative solution without the need of
an extra DB call and avp operations. This also does not seem to work if
there are multiple branches (multiple locations for the user) - only one of
them is relayed to the other proxy.
Thanks,
Adrian

Adrian,
I see. So on the proxy where you call add_path_received(), you don't
send out the request again but just call save() then? For such a
scenario it unfortunately doesn't work.

NULL so
------------------------------------------------------------------------
Hi Andreas,
I have set the configuration as you mentioned below but it does not seem
to help. Let me give you some more details about what I'm trying to
accomplish.
In my setup, there are 2 proxies: Proxy A and Proxy B. Depending on the
physical location, some users register to Proxy A and some to Proxy B.
The openser database is shared between the two proxies.
Here is the call scenario that I'm looking to get working:
1. User Bob registers to Proxy A with a particular NAT binding
2. External call comes in to Proxy B for user Bob.
3. Proxy B tries to contact Bob at the location from the usrloc table
but because the NAT binding does not know anything about Proxy B's IP,
the request is not passed trough.
What I need is for Proxy B to send the request to Proxy A so this can
then relay to client.
I have added the modparam settings on both proxies (since both can act
as both outbound proxies and registrar for different users) and added
inside the route:
...
If (uri == myself) {
...
If (is_method("REGISTER")) {
add_path_received();
...
I would have expected that this would add something to the 'path' value
in the location table, but this is still NULL after user registers.
Thanks,
Adrian

Hi Adrian,
I wrote the path module for exactly the scenario you describe here,
so
it should work for you as well :)
So, on your outbound proxy you have to set:
loadmodule "path.so"
modparam("path", "use_received", 1)
As well as something like the following in your routes:
if(method=="REGISTER") { add_path_received(); }
An on your registrar/proxy, you have to set:
modparam("registrar", "use_path", 1)
modparam("registrar", "path_mode", 0)
modparam("registrar", "path_use_received", 1)
Cheers,
Andreas

Thanks in advance.

list or anywhere a sample openser config that
uses it...
Sorry, I've not used it, but I'm 100% sure that it's what you
