Re: [SR-Users] Enable session_id in ServerHello for TLS

by Daniel-Constantin Mierla

Hello, thanks for reporting back it's working -- please keep the mailing list cc-ed, so people looking for same issue will be able to find it when searching the web archive. I am using snom3xx with tls and kamailio 3.x a lot, never had issues, but I have no clue about the softphone.exe Cheers, Daniel On 3/11/12 8:09 PM, Kristijan Vrban wrote: > Hello Daniel, > > many thanks for the fast reply, And yes, the session_cache option > solved my problem.

OT: is it allowed to send requests without waiting for the response of the previous request?

by Klaus Darilion

Hi all! I wonder if a presence server may send a NOTIFY if the previous NOTIFY in the dialog did not received an answer yet. I "grep"ed the relevant RFCs but couldn't find a definition. Thus, pointers are appreciated. Thanks Klaus

kamailio issues??? or ekiga problem??

by Vineet Menon

Hi, I just installed kamailio for my sip testing. I am using it for simple registrar purposes... The config file is default file with debugging enabled. I registered 2 UAs with kamailio, but am not able to call using aor dialing. I inspected packets with wireshark, which i think is a bit problematic. my server's at 31.21.33.238, while UAs are at 31.21.33.250 and 31.21.33.236. I have attached the wireshark file for packets. see packet number.5 and 7. Why has ekiga put the from field as ip:0.0.0.0.??? Isn't der something wrong here??? Regards, Vineet Menon

rfc: unique id for profiles

by Daniel-Constantin Mierla

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

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
