Yes, I do not need it.

I do not use keep-alive for SIP-over-TCP (or TLS), neither
- within the TCP layer (via its own mechanism), nor
- on the TCP layer (via CRLN).
Even short SIP-Register must be used carefully as explained by the author of Zoiper: <http://vimeo.com/82094736> and <http://vimeo.com/109598906>. Although the videos are 2 x 45 minutes long, I recommend them, to understand the frustrations of us mobile VoIPers.

System, in my case.
