setup a server SIP with TLS SRTP Encryption support

Hi, I have more than 7 years of experience in asterisk. I have done this work earlier. I can do this for you. Let me know when you want to start. Thanks vivek

Sorry bid 750$ by mistake thought its the minimum, My actual bid is 250$ Hi, I can build the system with TLS and SRTP support and can give you a demo of the encryption in one day, but ZRTP is actually not fully supported on Asterisk version above 1.4, which itself is very old build. if you have any ZRTP library that you have purchased for Asterisk then may be we can do it on latest Asterisk server. if just ZRTP is the need I can do it on Freeswitch with TLS and SRTP support. kindly let me know if we can have some chat about the project and we may discuss some discount as well. regards,

Hello, I have my own Centos 6.5 64bit which I could use for development purpose for testing the method I used is working. I also would use Xlite for testing the call dialing and receiving with encrytion support. So, once it works in my local, should be working also on your own. Let me know if this method OK for you.

Hello, I hope you are doing fine. I will setup Asterisk 1.8 or above which comes with SRTP and TLS on CentOS. I will configure your Asterisk to implement TLS to enhance the security. I will create key files and modify Asterisk's SIP configuration to enable TLS. I also modify the SIP client to connect to Asterisk over TLS. This involve in configuring Asterisk channel drivers that I would take care of those too. I should make sure that your client are compatible with TLS. If not, I will recommend you the client application that you should use. Please contact me to discuss the details. Regards, Ara
