by Nandini madhu

Dear All, I have integrated Kamailio (Version 4.0.1) with Asterisk (Version 11.4.0 rc1) server. I should have get VoIP features(call, SMS) with this integrated server. But when i tried to call other end SIP client through this integrated server, I'm getting this '*481 dialog/transaction does not exists*' error (please find the attachment 'call.pcap' below). SMS is through with the kamailio server without any problem (Find the attachment 'SMS.pcap' below). But when it comes to Calling feature, something is wrong and i am unable to find it. So please help me in resolving this issue. My system configuration is as follows: Host Architecture: i686 OS : Ubuntu 12.04 LTS Clients: Wi-Fi enabled VoIP phones. Find the attachments below for the kamailio configuration file and tcpdump based trace file for Calling to give a more complete picture. Any help will greatly appreciate. *Best regards, * Nandini

Re: [SR-Users] Does Kamailio provide any API for other program to create sip account

by Xiangwen Chen

Thanks David, My user account system is written in Python, can "kamctl" script be called in a python program? if not, can the user account system directly access the kamailio database, and do an SQL insert to create a new sip account? Thanks in advance!

Does Kamailio provide any API for other program to create sip account

by Xiangwen Chen

Hello, I am developing a sip VoIP app in IOS, which want to provide the feature of allowing user to create sip account from client side. I use Kamailio as sip server. My thought is when user register to the the user account system, the user account system can communicate with Kamailio, create a sip account associated with the user and pass the sip account to the client, the client then can configure itself using the sip account. Does Kamailio provide any API or module for me to do this? Thanks!

SIP Trunks Location

by Jose Suero

Hi I'm planning to set kamailio in front of an farm of pbx servers (haven't decided on freeswitch or asterisk) there's a million tutorials on how to do this, what I haven't found is what part of my setup actually handles the sip trunks my phone company provides me with. What's the best practice when It comes to this? Is kamailio going to be receiving the calls from the trunk and passing them to the PBX or is it the other way around? please advice Thanks in advance Jose Suero
