Sipsak Limitations

No tool is perfect! Here are some limitations you should know about:

\n < li>The hostname used in the Via line isn’t always accurate. This can happen with the loopback interface or if there are multiple interfaces on a host. The rport parameter helps fix issues with incorrect hostnames, but older implementations may still have trouble.\l >\ n\n \u2022 DNS responses aren’t fully parsed, which might lead to odd outputs during hostname detection.\u2022 TCP transport protocol isn’t supported.\u2022 No support for IPv6 transport protocol either.\u2022 Missing support for Record-Route and Route headers.\u2022 Not fully compatible with RFC3261.\u2022 A few smaller problems listed in the TODO file need attention. \

What's New in This Release?

This release comes packed with exciting updates:

< li>A new option lets you add any header to outgoing requests. \ n< li>The variable replacement now accepts an unlimited number of attribute-value pairs. \ n< li>SIP now supports SHA1 along with MD5 as a digest authentication algorithm. \ n< li>Password for authentication can be read from stdin, which helps keep your password safe from prying eyes! \ n< li>Bugs related to running as user root have been fixed, plus it compiles fine under Cygwin again!
