Re: [Serusers] 2 questions regarding user location

Hi, I have two questions regarding user location. 1) Is there a way of getting the user location info for manipulating it in ser.cfg ? Something like lookup but without rewriting anything. Basically what I want to do is check if the caller and the caller are NATed and belong to a certain same network then I should not use media proxy. The criterion for the same network would be that both sides are originating from the same public ip. Thus I would have to retrieve the "received" field value for the calee and compare it with the ip contained in the contact header field of the caller in the INVITE . Perhaps there is also another way to do this?

2) What happens when I have multiple phones registered under one user? How lookup(location) works when I have more than one ips in location table for the user? During tests I had a UA behind NAT registering to SER with an ip assigned from the dhcp. After a while I had the UA assigned a different ip from the dhcp and the Register on SER under the same user name. The problem was that during registration SER would respond back to the UA for requesting authorisation credentials but when it was time to send the 200 OK message for registration , it would send it only to the previous location of the UA and not the one it sent the REGISTER message from with of course failure to register because UA would not get the OK from SER. I noticed that in Contact header of the 200 message there were more than one return ips (the old one and the new one), Of course as soon as the old location timed out the registration would go ok.
