Dear Daniel, Thank you for your previous reply. I am working on Kamailio (V 4.0) server to bring up VoIP features (Voice call, SMS) on my Hand-held, Wi-Fi enabled devices (Which are not GSM supportable). 1) I would like you to confirm that, is this Kamailio architecture supports SMSing feature for end-to-end IP solutions? (without GSM module). 2) And i am also focusing on Kamailio integration with Asterisk server, so is there any scope of get through my requirement (SMS on Kamailio server through end-to-end IP) in this integration case? I hope you could help me in getting clarity about this. *Thank you and Best regards,* *R Ravindra **Gowda* *Engineer - Systems and Products*. *Thrikasa Technologies* *| Office: +91 40 23260434 | Mob: +918885284050 * *| Fax:+91 40 23221045* *| email: ravindra(a)thrikasa.in* *| Web: www.thrikasa.in* 'If you don't give up,you cannot fail'.

Otherwise, send to sr-users if you have questions about how to use kamailio and to sr-dev only for questions related to new features development and unstable branch. To help you, grab ngrep trace of registration and see who is sending 401. If it is kamailio, then restart it with debug=3 in configuration file and look at the logs to see why is not authenticated. If you fail to understand the problem, send both ngrep output and syslog messages here.
