Need help with Routing presence NOTIFY messages
by Veerabhara Gundu 09 Jul '14

09 Jul '14

Hello Experts, I have two Kamailio servers with built in presence servers with load balanced with DNS, both sharing same data base. Registration, authentication and messaging are working without any problem. When it comes to Presence, NOTIFY messages generated by Kamailio is getting rejected by firewall if the client didn't register to that particular Kamailio. In MESSAGES case, I read the socket info from Location table, if the client is not registered to that Kamailio forwarded to the server which serving that user. But in NOTIFY case, these messages are not coming to routing logic at all, Kamailio is directly sending messages by looking at the contact information from active-watchers table. One possible solution I am thinking is, separating presence logic and starting that as separate server. That way I can play with contact header. Any other thoughts, I appreciate any help with this. I have spent enough time on this. Thanks, Veera Thanks, Veera

Re: [SR-Users] What is q-value ??
by Daniel Grotti 09 Jul '14

09 Jul '14

Hi, q value is used in location table for serial forking. If you have a subscriber with 2 contact registered you can use the q value to load one contact first (the one with the higher q) and afterwards load and call the second one. Highest is the value stored, highest is the priority.

I want to extract domain attribute of a user from Location Table. I have gone through the readme of registrar module, that has an example of using reg_fetch_contacts() and how to access the attributes of a location record ? But I get the callee domain = NULL when I log using command xlog("callee=>domain: $(ulc(callee=>domain)))\n". Can anyone please help me with the correct syntax. Thanking in advance. -- View this message in context: http://sip-router.1086192.n5.nabble.com/Access-the-attributes-of-a-location… Sent from the Users mailing list archive at Nabble.com.

Hi, I had installed kamailio on my AWS EC2, by following the steps in http://kamailio.org/docs/install/INSTALL.kamailio-4.1.x .

Kamailio, CPL, SIP CGI and alternatives.
by LAA 08 Jul '14

08 Jul '14

Hi all, I'm looking for a mechanism to let users personalize the behaviour of their profile, uploading configuration changes to Kamailio. For example voice mail redirecion, time-based routing, etc. I'm testing CPL scripts (cpl-c module with Kamailio 4.1.3), but I have problems with the behaviour of some features. "reject" and "redirect" seem to be working fine, but "proxy" is not working. ¿Has anybody experienced the same problems? I could hardly find any post regarding CPL scripting with Kamailio. What are the most commonly used alternatives for this purpose with Kamailio? ¿SIP CGI? ¿any other? Best regards. Luis.

SDP_NAT on Retry
by Timo Klecker 08 Jul '14

08 Jul '14

Hello everybody, we have got a problem with sdp-nat on retries of a 200 OK packet. Due to slow response of our trunk the 200 ok is resend (up to 3 times) but sdp-nat is only done on the first two packets. We are running Kamailio 4.1.0 with the following setup: Trunk --> NAT --> Kamailio --> Voip Bridge The rtp stream from the trunk (public ip) is supposed to go to one of our media gateways (behind 1:1 nat). We use sdp_mangle_ip to replace the private IPs of our Mediagateway with the public ones. This goes well with the first 200 OK packet but not with a retry. A.A.A.A (public trunk media IP) B.B.B.B (our public media IP - 1:1 natted to I.I.I.I) INVITE Trunk --> Kamailio Connection Information (c): IN IP4 A.A.A.A INVITE Kamailio --> Voip Bridge Connection Information (c): IN IP4 A.A.A.A 200 OK Kamailio <-- Voip Bridge Connection Information (c): IN IP4 I.I.I.I 200 OK Trunk <-- Kamailio Connection Information (c): IN IP4 B.B.B.B 200 OK Kamailio <-- Voip Bridge Connection Information (c): IN IP4 I.I.I.I 200 OK Trunk <-- Kamailio Connection Information (c): IN IP4 I.I.I.I ACK Trunk --> Kamailio --> Voip Bridge Our configuration used is the following: route[RELAY] { xlog("L_INFO"," In route Block RELAY \n"); # enable additional event routes for forwarded requests if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } if (!t_relay()) { xlog("L_NOTICE", " (ROUTE_RELAY) Relay failed, sending error \n"); sl_reply_error(); } exit; } onreply_route[MANAGE_REPLY] { xlog("L_INFO"," In route Block MANAGE_REPLY \n"); if ( isflagset(20) ) { -- we have to do nat route(SDP_NAT); force_send_socket(KAMAILIO_TO_TRUNK_IP); } else { force_send_socket(KAMAILIO_TO_BRIDGE_IP); } } How can we handle the 200 OK retry? Is there a way to do this? Kind regards Timo Klecker
