Dear Friends, In case of a call failure I'm trying from failure route to send the call through other gateways with Dispatcher module. I would like to have ACC for all failures that a call can possibly pass. If the call fails in the 3 first gateways I want them also in my mysql ACC table. I tried that with AVPs in the syslog and it works fine BUT is there any way that I can simply setflag(1) for accounting and I can have ACC for every try? I tryied to add in failure route : setflag(1); # do accounting ... setflag(3); # ... even if the transaction fails but I'm getting ACC only the last try. Thanks Alex

[Kamailio-Users] TLS Multiple records not read

by Jijo Jose

Hi All, We have a SIP server which enabled NAGLE algorithm and proxy as openser ver 1.1 SIP Server send a TLS multiple records( 2 SIP messages) in a packet to openser. Openser is reading only the first record( first SIP message). The second TLS record(sip message) is read only when the next message recieved by openser from the SIP Server. I would like to know anybody observed this issue. I have compared the codebase of kamailio 1.4 and openser 1.1 but didin't find any diffrence for TLS. I have looked at the API _tls_read() in openser which is same as that of kamilio. Don't we need to use SSL_pending() after SSL_read() to verify any buffer is left in the SSL layer ? Do you think is it due to the poll method error? The poll method we use is POLL_SIGIO_RT Please let me know your comments. Thanks in advance. Jijo

[Kamailio-Users] state field on dialog table

by Panagiotis Skoulikaritis

Hello I have a question about the state field on the dialog table. I guess it is more sip protocol oriented than kamailio deployment, I assume that the values (1-5) that are logged are the state of the dialog correct ? and if the above are correct the dialog states are the following ? 1. waiting for UAC deciscion 2. Initiate dialog 3. Establish dialog 4. Stop Media 5. Destroy dialog I apologize for my sip ignorance Trying to build up my knowledge. :) I' m asking this because I' m trying to export statistics about the calls that are handled from the kamailio and the state of the call for specific users,IP's, destinations. Thanks Panagiotis

Hi, I've installed Kamailio 3.0 on RHEL5 and activated the mysql backend and tls support. Everything works fine with Soft User Agent "Phoner lite". My Problem is: If I try to register a "snom 370" Kamailio crashes immediatly. What is wrong? Any suggestions?

[Kamailio-Users] Asterisk 403 Forbidden error with port translation

by Vikram Ragukumar

Hello, I have made some progress since my previous post, but not enough :). ------------- -------- --- -------- |Sip Softphone|-------|Internet|--------|F.W|-----|Asterisk| ------------- -------- --- -------- IP addresses: a.b.c.d q.w.e.r The SIP softphone(x-lite) is configured to register with the asterisk server through port 9090 (Domain q.w.e.r:9090).Firewall(F.W) is setup as the outbound proxy for the softphone(Outbound proxy a.b.c.d:9090). Authentication credentials for the softphone match the user registered in asterisk's sip.conf. F.W runs Kamailio and rtpproxy, with Kamailio listening on port 5060. The asterisk server is setup to listen on port 5060. The Firewall(F.W), uses a libnetfilter_queue based program to : (a) Rewrite the destination port 9090 as 5060, and rewrite all other occurrences of 9090 as 5060 in the SIP message, for packets from the softphone to the asterisk server. (b) Rewrite the source port 5060 as 9090, and rewrite all other occurrences of 5060 as 9090 in the SIP message, for packets from the asterisk server to the softphone. The following exchange of SIP messages take place -Sip softphone sends a REGISTER message to asterisk -Asterisk responds with a 401 UNAUTHORIZED -Sip softphone replies with a REGISTER message containing auth. info. -Asterisk responds with a 403 FORBIDDEN : BAD AUTHORIZATION The above setup works when the softphone uses port 5060, so there problem here does not have anything to do with Authorization credentials. Is it possible i might be modifying parts of the packet that shouldn't be modified or i might not be modifying some relevant parts of the packet ? Thanks in advance, Vikram.

[Kamailio-Users] Script variables Question

by alex pappas

Dear friends, When a sip 4rU is entering my kamailio script I'm cutting down the prefix of this customer and added to a script variable. In the same same route after i do some checks then i add back the customer prefix which I had kept in the script variable. The problem: Some times the call goes to failure Route for rerouting and then i try to add the prefix again but the is empty. How can I transfer a variable from route to route and be a unique variable for each call? Thank you Alex

[Kamailio-Users] concurrent dialogs

by alex pappas

Dear Friends, I have the following question: When I'm running the command *kamctl fifo dlg_list* I'm getting the concurrent dialogs in that moment. When I disable the sip_trace module(which I don't see how they are related) I get NO output when I run the same command. Does anyone knows on why this is happening ? Alex
