    Default SIP over TCP

    Any chance we’ll see this in the near future? The reason I ask is because, particularly with “smartphones” and 4G becoming more prolific, there are many advantages to SIP over TCP. These include, but are not limited to, the following:

    • More reliable call reception (mostly due to aggressive UDP state timers by mobile providers)
    • Improved battery life for mobile devices as they do not have to wake to send keep-alives as often and, consequently, they use their radios less
    • Reduced server overhead due to reduced keep-alive signaling and response
    • More firewall friendly
    • Improved NAT traversal (will only get worse until IPv6 becomes more prolific)
    • Required for possible SIP over TLS
