  In your own sandbox, feel free to do whatever you want. If the companies you
  promote asterisk to are going to call only you, feel free to promote
  whatever you want to them. But if any of them want to be
  interoperable with the rest of SIP-world, please STOP telling them to
  use A records instead of SRV. That way you are forcing others to do
  hacks they do not want to do !

  SRV is essential for SIP, whether you like it or not, and there are
  companies out there that rely on it.

  Moreover, SIP is not just asterisk. You have absolutely no idea how
  many other SIP implementations are out there, you have no idea whether
  they follow RFC3265 or not, you have no idea how many companies rely
  or SRV. Nobody knows this and it is clear that your arguments are
  based on what do you *THINK* others do. And this is very bad because
  it kills interoperability.

  So, please, stop promoting using of A records instead of SRV, that would
  make our life a little bit easier, thank you.
