PPTP and SIP routing troubles

[ ramblings ]

Adding some creative routing for SIP server seems to work, but this
also needs to do the RTP servers, which seem to be different.

There are several issues:

  - routing setup on both sides.  one side is complex since it has
    multiple hosts.

  - does sip have multiple hosts?  a bit
    provider-dependent.. depending on how the load balancing works,
    there is no real reason to keep RTP server stable.

  - PPTP DNS: it helps to override some hosts on the local net / VPN
    to patch directly to a local IP.
