[asterisk-users] sip forking needed for ekiga 3.0

[SIP]

A machine with more than one default gateway is a VERY special case
(used for load-balancing or possibly failover). Most systems will not
allow it. I mean... logically, it's odd. Default means "when not applied
to any other special rule, I choose this one."    Not this two. Not this
three. This one. It used to be called the Gateway of Last Resort. Last
being final and not penultimate.

With that being said, if you somehow manage to get by the internal
consistency checks and more than one interface (and by interface, I also
mean alias, as those are 'virtual interfaces') matches the default
gateway, your machine is misconfigured and internet traffic will not
properly flow.

I know you're just the messenger here, and it's not your fault. But the
message is wrong. Ekiga has tried to solve a problem (that of
determining a 'best path' for SIP to allow data flow in a NAT or
filtered scenario) using poorly thought-out logic. While there may be
any number of SIP proxies out there (SER is one of them, and I know
that's what the Ekiga service uses) that might be able to handle a
mistake on the client side with ease and grace, there's no guarantee
that they all will, and assuming they will simply because your test
environment allows it is lazy.

The RFCs are there for a reason. All SIP forking is UAS territory. Not
UAC territory.
