[Users] Newbie questions
by Saúl Ibarra 14 Nov '06

Hi I'm new at using OpenSER. I plan to use OpenSER with a SIP proxy (rtpproxy?, mediaproxy?) in order to handle SIP client registrations and connections behind NAT, and then I want to pass the control to an Asterisk server, in order to make the call over an IAX trunk. I've been reading quite a lot documentation on both SER and OpenSER, but I can't figure out how to do it properly. Is there an example or a guide I can check? Thanks in advance. -- Saúl -- "Some people say why, other just say, why not." http://saghul.wordpress.com/

[Users] UAC module. CANCEL request handling.
by Leonid Fainshtein 14 Nov '06

14 Nov '06

Hi, I try to use the "UAC module" for replacing header field "From". I defined the automatic mode for "From" restore (modparam("uac","from_restore_mode","auto")) and change "From" only for INVITE requests. It looks like I also have to change manually header filed "From" also in CANCEL requests. It is because UAC (call originator) sends CANCEL without header "Route" and therefore OpenSer can't perform the automatic replacement. Do I miss anything? Is there a way to implement automatic header field "From" handling for the CANCEL requests? Thank you in advance, Leonid Fainshtein

[Users]Can OpenSER uses same TCP session from the registration in some TLS case?
by Pat wang 14 Nov '06

14 Nov '06

Hi, I am working on the TLS with OpenSER and I found an something interesting. If an INVITE received by OpenSER with a Request-URI of the client AOR then OpenSER proxy the request via the same TCP session established during registration. If the INVITE has a Request-URI of the client's contact URI then OpenSER start a new TCP session. For example: One Eyebeam registers with AOR as: user1(a)tlstest.com and has a contact URI of user1(a)192.168.100.1. When an INVITE contains a RURI as user1(a)tlstest.com then OpenSER look up the location table and replace it with the user1(a)192.168.100.1 then proxy it via the same TCP session as the one during the registration. If an INVITE already has RURI as user1(a)192.168.100.1 then OpenSER proxy this INVITE by starting a new TCP session and Eyebeam does not accept the new session. The call will be failed in this case. I can't find any solution to fix this issue. Could someone know this issue please give some advice?

[Users] OpenSER not working after running for several days
by Papadopoulos Georgios 14 Nov '06

14 Nov '06

Hi Richard, This is a very interesting discussion. However I don't think our situations are similar. Just to make it clear, in your case, did OpenSER slow down or stop working at all? Was it something that happened gradually? In my case, it runs fine for several days. There are no delays, no slowing down of any kind. Then suddenly it stops responding. There is no script change, nothing at all. Actually most of the times it happened during the night when there is nobody around "playing" with DNS, network settings etc. So what could be causing this? Can I set up some sort of logging that will help find the cause of this? I have no clue what kind of information I should be logging. Most of my troubleshooting is done with ngrep. I could redirect this to a log file, but with the volume of traffic that we have, a few hours would be enough to fill the disk. thank you for any help George Disclaimer The information in this e-mail and any attachments is confidential.

[Users] TCP REGISTER
by Russ Daigle 14 Nov '06

14 Nov '06

When I REGISTER for UDP, I receive subsequent requests for that user. However, when I perform a TCP REGISTER, even though the register returns 200 OK, no requests make it to the user. Is this supported? It should be. However, I noticed when you do a "openserctl ul show" command, it shows users, but it doens't indicate whether they are UDP or TCP registered. -Russ

[Serusers] SER pre-release - Presence and NOTIFY
by SER LIST 14 Nov '06

14 Nov '06

Hi, I have SER Proxy and PRESENCE running on different machines. REGISTERS are being forwarded by SER Proxy to PRESENCE and PRESENCE is storing the location information in "location" db. What I am seeing is that when the PRESENCE Server sends NOTIFYs to watchers, it sends them to the SER PROXY (destination IP Is that of SER PROXY) but the URI in NOTIFY is that of the watchers LOCATION INFO. Is this correct? I would like the NOTIFY URI to contain the SIP DOMAIN and not the contact info. e.g. user 444 registers with SER PROXY (sip.xx.com). It is registering from 10.1.1.1:12321 (location info). SER PROXY sends the REGISTER TO Presence server which stores this info in location database (location is 444@10.1.1.1:12321). Now when Presence Server sends NOTIFY, it sends it to the SER PROXY IP BUT the NOTIFY URI IS: NOTIFY sip:444@10.1.1.1:12321 SIP/2.0 How can I have the NOTIFY URI to be : NOTIFY sip:444@sip.xx.com SIP/2.0 Any suggestions would be higlhy appreciated. _________________________________________________________________ Ready for the world's first international mobile film festival celebrating the creative potential of today's youth?
