rfc: unique id for profiles
by Daniel-Constantin Mierla 13 Mar '12

13 Mar '12

Hello, from the last IRC devel meetings discussions, one topic was about adding an unique id field per user profiles, with the decision to bring it to mailing lists for broader audience. That will help to reference easier across records. At this moment, the most relationships are via (username) or (username,domain) when use_domain=1, bringing some complexity. The main reasons I came up to this were: - in the perspective of gruu implementation for usrloc, with global addresses, an unique (opaque) id seem to simplify things, no matter SIP address of the user changes or not -- the public gruu id can be different than the internal one, though - it will open a new group of K and S modules for merging, S using unique ids mostly everywhere Moving towards it will be done gradually, keeping backward compatibility for a while. The first steps will be to add new column in few tables (subscriber, location), the username/domain columns will stay there forever in most of the cases, they will become additional info over the time (e.g., primary sip address in subscriber). From the point of view of filling up the column, can be as simple as setting it to username@domain, or generate some unique string with tools out there. Overall, there will be a bit more db space used at the benefit of reduced complexity in the code. Jason Penton mentioned that IMS architecture relies also on unique ids. Looking forward to comments, alternatives, etc ... sr-users community was cc-ed because it is not strictly technical discussion/decision.

Hi Daniel, Thanks! I changed to use the $avp() syntax and that fixed it. The examples I followed was from an old wiki.

Registration Limits
by Reda Aouad 12 Mar '12

12 Mar '12

Hi, Is there a way to ensure single-registration per user-agent for a user, which overwrites previous registration ? Or is there a way to limit the number of registrations per user, but overwriting the earliest registration for each new one ? Thanks, Reda

Kamailio + Asterisk, what happens when limit for gateway is reached
by Sasa Vilic 12 Mar '12

12 Mar '12

Hello, I have read here about load balancing between multiple gateways by using carrierroute module, but there is one particular question for which I found no answer. Let's say I have two asterisk servers (X und Y), that are my gateways to PSTN. Let we do it simple. Let's say that each gateway supports only one outgoing call at the time and there is no incoming calls from PSTN. Now: Bob calls one number and Kamailio uses X gateway. Alice calls other number and Kamailio uses Y gateway. Alice terminates the call. Alice place a new call, but Bob's call is still in progress. If we were used round robin algorithm, Kamailio would then use X gateway, but X gateway is currently occupied. What shell happen now? And what if Alice didn't tear down call ordinary? What if it her SIP client simply crashed? (Then kamailio would think that there is now free gateway) So the main question is: can kamailio know/detect, how much calls are going over one particular gateway and what can be done when limit for this gateway is reached? Thank you in advance. Kind Regards, Sasa Vilic
