[Asterisk-Users] Digium should develop and sell just Dummy card. For timing...

[Richard Alexander]

Asterisk was being used for TDM based PSTN switching before if even
supported SIP. There is therefore nothing strange about it using
hardware based timing. I don't see the relevance of VoIP transmission to
the discussion. Sure you can squirt it down the tube as you see fit -
but MOH is a different beast and therefore VoIP only systems using MOH
still need a suitable timer - and there have been several attempts at
workarounds.

In any case even if you can squirt VoIP packets as you please you still
need a timing regime to support a pseudo real time app on a far from
real time OS.  A system that comes from a T1 background using a hardware
timer seems quite understandable.
