Lucas, When you restart Asterisk, all registration information is lost. The clients must resend their registration information. This has nothing to do with Kamailio, all it does is forward the registrations (as you said). Unfortunately, on an Asterisk reload, all that information is lost. For further information please ask in the Asterisk mailing list.

That would mean that you have reach someone ALSO without knowleadge about how SIP works, that's all. It have no sense at all ... Kamailio only forward your request, it could not "re-register" or "fake-register" your UAC's agains your Asterisk boxes without knowing all the passwords of the UAC's, also it would have to behave as every UAC that was registered (that means, faking it's IP's, contact uri's, ports, etc.), because REGISTERing it's not only a matter of seding a request, you must take into account the replies and so on. So, again ... please, FIRST read, read, re-read, re-re-read, about how SIP works, then come back with a smarter question and i'm sure you will get the help you need.

All, I have SER sitting in front of Asterisk. It is useful to me for Call Forking purposes as I do not think Asterisk handle multiple registered endpoints (against a single username) However, since both SER and Asterisk are Registrars, and Asterisk need to know register info to work properly, I need to forward Registers from SER to Asterisk.... It works ok, but it means I have to turn off the RFC2617 auth mech on Asterisk.

In this scenario, SER is not acting a UAS; it is not the logical target of the REGISTER request. Therefore, it is not behaving as a "registrar." Only Asterisk is the registrar in that scenario. There is nothing in RFC 3261 preventing you from fronting a registrar with a proxy and statefully relaying REGISTER requests; in principle, a proxy can forward any request. However, proxies (and UASs) cannot add Record-Route headers to the request, and since REGISTER does not establish a dialog, route sets have no meaning in relation to it anyhow. This means there is no way to establish a pre-determined route set in any scenario ("trapezoid") involving one or more proxies between the registrant and the registrar. The solution to that problem is Path (RFC 3327). -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/

Iñaki it's ok, on you scenario, that question is ALL RELATED to Asterisk, not to Kamailio, that it's acting only as a forwarder. Best regards -- Raúl Alexis Betancor Santana Dimensión Virtual
