I am working on VOIP calls integration in Android using SIPDROID. Here I want to encrypt data while sending and decrypt after receiving the data. I have gone through the code but confused as to which class file I should use for encryption and decryption of data.

  • CSipSimple (http://code.google.com/p/csipsimple/) is a free (GPL) SIP client for Android which supports TLS out of the box. It works great -- why not use it? – wau Jul 29 '13 at 13:22
  • @wau: TLS is for SIP signalling encryption..while to encrypt media you need SRTP..does CSipSimple supports SRTP? – Harsh Vardhan Dec 02 '13 at 05:48
  • Yes it does. Afaik, for secure calling, you need both media and SIP encryption, since SRTP keys are exchanged using SIP. – wau Dec 03 '13 at 10:01
