How will you do ulaw <-> gsm without transcoding?

A whole bunch?
It's hard to give any specifics without the same hardware and workload.
Here's a datapoint to consider -- testing an HP ProLiant DL320e Gen8 v2
E3-1240v3 8GB. 9300 passmarks vs your 7300 passmarks. (And only $880 from
Newegg.)
2 hosts, 1 originating calls, 1 running a simple dialplan, but similar to
the expected production dialplan.
500 'participants' - 100 meetme conferences with 5 calls in each.
3000 'participants' - 100 confbridge conferences with 30 calls in each.
Meetme() is still a 'single thread' application so you're done when
you
max out 1 CPU core.
500 calls was my goal, so that's where testing stopped.
The hosts aren't in production yet, so I don't know if my testing
experience will match production experience.
I would expect playback() (without transcoding) to be significantly less
CPU hungry than meetme() or confbridge().
