Dear Karim, Thank you for your reply. Yes you are right. I have having difficulty searching for this for past 2 months. Yes. Here is what i want. Once i receive the REGISTER messages, my SER will send out "INVITE" message to my other clients. This is what i am intended to do. However, i could not search for the right coding inside the ser-0.9.6. Please advice and apologies if any inconvenience caused for you. Thanks.

If it's the case you can make a condition in the "ser.cfg" file, in the bloc "route{ ... }". for example: route { if (method == "REGISTER") { #what you want to do}; } 2007/3/3, Goh, Tee-Yong <gohty(a)m1.com.sg >: -- BASRAOUI Karim www.basraouik.afrikart.net ------------------------------ This email (including any attachment) is subject to the following disclaimer: http://m1.com.sg/M1/misc/disclaimer ------------------------------
