[Kamailio-Users] Multiple SIP Proxy Environment / Socket Information

by Brandon Armstead

Hello guys, Is there a method upon using lookup("location") to also pull out the "socket" information for the original location the UAC registered to, for scenarios of this example: P1 & P2 share same usrloc database. UA1 registers to P1 UA2 registers to P2 UA1 calls UA2 UA1 invites -> P1 -> INVITES -> UA2 (bypassing P2 -- where the actual nat binding is). Now upon P1 looking up usrloc for UA2, I would like to recognize that P1 is not the Proxy to deliver the call, and forward the request to P2 to send to UA2. So currently I have: UA1 INVITE -> P1 INVITE -> UA2 I wish to have: UA1 INVITE -> P1 INVITE -> P2 INVITE -> UA2 Is there an easy method to do this? I have been looking at the new nat traversal module it looks like it is doable with this (any further input as far as that?). Also is it possible with the classic Nat Helper module? Any input is appreciated, thanks!

[Kamailio-Users] LCR Private Memory

by Stagg Shelton

I am working to get LCR implemented on my migration system, and when I try to start kamailio i find the below information in the log file, and kamailio fails to start. My lcr table has 30667 rows in it. I have read about changing the config.h file to increase the private memory, but my question is how much should I allocate. I forsee going up to more than 200,000 routes within the next 12 month period. I am currently working towards migrating up from openser 1.3.3 to kamailio-1.4.4-notls. I am currently not using LCR in my production openser 1.3.3 system. This is new functionality that we are implementing as part of the upgrade.

Hi all, just installed SIREMIS on a Ubuntu server, on top of kamailio 1.5. It seems to work alright, but for the charts sections.

[Kamailio-Users] from replace

by Gentrice's kaiser

Dear Sir: I wrote a failure route for serial call mechanism, it help for no answer call ... but all these serial calls need to have a new CallerID, so I use replace_from for this purpose. modparam("uac","from_restore_mode","auto") failure_route[3] { log(1,"******* I'm failure_route[3] *******\n"); if (avp_pushto("$ru", "$avp(forward)")) { append_branch(); avp_delete("$avp(forward)"); uac_replace_from("sip:1234@$fd"); # change from header t_on_failure("3"); # try next , recursive t_relay(); } } If only one forward number in AVP array , this code working fine, the issue will happen if multiple forward number trying, ( forward 2nd,3rd ...number) the UAC module will restore from header in 200 OK of its following message when a UA answered, we will have a duplicated "from header" in 200 OK (sending out opensips). It means we will have 2 "from" headers (in 200 OK) to caller, if 2nd forwarded callee answer. Caller ---> Invite ---> opensips ----> UA 0, no answer ----> UA 1, no answer ---->UA 2, answer <----200 OK <---200OK<--- this 200ok will have 2 "from" header. Most of UA just ignore redundant from header, but some can not. I think it should be UAC modules issue, anyone can help me? best regards KK

[Serusers] SIP Diversion for SER 0.9.6

by inge

Hi all, I look for a way to use SIP DIVERSION. In case of a call transfer, I have to conserve the original called number and send it to SS7 gateway. But for a good interoperability between SIP and SS7 in this kind of application I just see the way of SIP DIVERSION support. Can someone help me ? Regards, A.L

[Kamailio-Users] insert_hf not persistant

by David Aldworth

I think I hijacked a thread when I posted this previously. Sorry 'bout that. The issue we are having is where Kamailio relays an INVITE with the correct To header field domain, however when it relays the subsequent CANCEL it seems like it does not correctly change the To header field domain. Here is what we use to try and put in the correct To header in the CANCEL: remove_hf("To"); if ($tt == null) insert_hf("To: <sip:$rU@1.2.3.4>\r\n", "From"); else insert_hf("To: <sip:$rU@1.2.3.4>;tag=$tt\r\n", "From"); xlog("DBG1: Trying to fix CANCEL: td=$td ci=$ci rm=$rm ru=$ru ou=$ou\n"); Changes to the left side of the at-symbol persist, however changes to the domain are reverted and changed back to what was received from adjacent proxy. Any ideas why it reverts?

[Kamailio-Users] \0 in SIP-Messsages - uac_replac_from - Lumps - etc...

by Carsten Bock

Hi, short question: I've noticed, when the UAC-Module (from 1.3) replaces the From-Headerin subsequential requests, the From-Header is filled up with "zeros". For most clients this is absolutely fine (tested with Snom's, AVM's, Cisco's and many more). I've noticed, that some Zyxel devices however do not like this and ignore the request in this case... Is this somehow defined in the RFC? Can somebody give me hint on a chapter or something? Or does it break the RFC? Thanks in advance, Carsten
