Hello everybody,
I just started to use kamailio. For the basic functions, I can get them working properly.
But when I started to write my own script, I encountered some problem.
The scenario is like this:
I have a linksys spa3102 pstn-voip gateway at home which register itself at my server on the internet. I use adsl at home so the ip address change dynamically. When I want to route all my pstn calls to spa3102, I have to figure out the current ip address of my home connection. I tried to use dynamic dns, but my router does not update the ip address sometimes. So I was thinking about solving this problem in the kamailio configuration script.
All I need is to get the registration information of spa3102 so that I can route my pstn call to it.
I guess there might be a function doing this work. It expect a subscriber name as a variable and returns the registration information of the subscriber. I tried to dig the function out of kamailio documents but failed. And google doesn't seem to provide much help. I don't know if this function exist or not. Could someone confirm my guess or point out where I can find it? I will be much appreciated.

Hello,
the lookup("location") is the one that you look for.
In this particular case, you have to make a backup of r-uri username, change it with spa3102 username, do location lookup and then set back the r-uri username with pstn number and relay.
There is a function to fetch details of registered contacts for a user, see readme of registrar module, but then you have to set manually the destination address details.
Cheers, Daniel

That's what I'm looking for. Thank you very much.
Here is my final script:
reg_fetch_contacts("location", "sip:gatewaynumber@mydomain.com", "pstn"); if($(ulc(pstn=>count))){ $ru = "sip:" + $rU + "@" + $(ulc(pstn=>addr){uri.host}) + ":" + $(ulc(pstn=>addr){uri.port}); } else { # fall back to old ddns style gateway address $ru = "sip:" + $rU + "@" + $sel(cfg_get.pstn.gw_ip); } route(RELAY);
