INVITE to 200, INVITE to 404, INVITE to 487

by Luis F Urrea

Hi all, I have seen Siremis charts that account stats such as INVITE to 200 and INVITE to 404. I would like to have this sort of accounting but without the use of the Siremis UI, so I am wondering how is this achieved, is this done through the ACC module and correlating responses? TIA

Path attribute not updated in location table when user switches between two access points behind NAT

by Prasun Bheri

Hi Group, I stumbled upon a possible bug in Kamailios (4.0.0) Path module. Setup: Proxy server is behind another Kamailio Load Balancer and both (Proxy & LB) are configured to use Path module. When client registers for the first time path is inserted into Location table successfully however when client switches from currently Access Point to another AP (which are both behind a NAT), Path attribute in Location table is not updated with newer <ip>:<port> When client switched from one AP to another, IP remained same however port changed from 48238 to 33038 and subsequent update query issued by Kamailio is as follows: update location set expires='2014-07-11 19:27:32',q=-1.00 ,cseq=1805331004,flags=0,cflags=64,user_agent='xxxxxxxxxx',received='sip:xx5.xx1.xx1.219: *33038*;transport=tcp',path='<sip:xx3.xx1.xx9.53;transport=tcp;lr;received=\'sip:xx5.xx1.xx1.219:33038;transport=tcp\'>',socket='tcp:xx3.xx1.xx9.28:5060',methods=16351,last_modified='2014-07-11 18:27:32',ruid='uloc-53bf7f9c-4254-e',instance='<urn:imei:911304251588897>',reg_id=1 where username='testuser' *AND **contact='sip:testuser@xx5.xx1.xx1.219:33038;transport=tcp' *AND callid='7983ce39-2ffd3a92-8f82f477-e6313128-84b64128' AND domain=' vvoip.xxxxxxxx.com' In the where clause contact should have been old value taken from initial registration, however contact from new registration is used, so where condition always fails and entry is never updated. as a result no further calls or messages could be received by the client. is there any workaround for this issue? PS: Here is the configuration of path module. # set path to lazy mode modparam("registrar", "path_mode", 1) # set to 1 to use path header modparam("registrar", "use_path", 1) # set to 1 to use path received parameter modparam("registrar", "path_use_received", 1) modparam("path", "use_received", 1) Thanks & Regards, Prasun

Listen to to 2 NIC's IP addresses and establish call between

by Raj Roy Ghandhi

Hi Friends, I have to configure a Kamailio in to meet following requirements 1. PC having 2 NICs (NIC-A and NIC-B) with 2 different IPs (IP-A and IP-B) from 2 different service providers. Totally 2 different IPs. NIC-A attached to provider is a private SIP traffic provider and having IP-A. (no internet access) NIC-B attached to internet service provider and having IP-B. 2. I get SIP traffic to IP-A of NIC-A from SIP traffic provider. 3. I need to forward that SIP traffic to another SIP carrier in remote location using IP-B of NIC-B through internet and have the call establish without any issue. How can I achieve this with single instance of Kamailio running on same machine. Please advice me. Best Regards, Roy.

crash after 100 trying on NOTIFY

by Kristian F. Høgh

Hi, We've had the following crash. Kamailio 4.0.4 Client sends SUBSCRIBE, kamailio answers 202. Kamailio sends NOTIFY, client answers 100 trying. fr_timer is 5000. The client doesn't send "200 OK", so kamailio generates 408. Any suggestions?

Need help with Routing presence NOTIFY messages

by Veerabhara Gundu

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

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.
