asterisk users - Oct 2012 - conversion?

Hi,

Perhaps can someone tell me if i had the wrong expectancies....

If one sip-clinet only supports GSM-codec, and another only supports
g711-U, they still can call each other and asterisk does the transcoding
Correct?

If i try to do the same with an AV-call, (one only h264, the other only
h263) there is no video-transcoding, and you get an audio-call only.

Sure, video transcoding is probably horrible CPU-expensive, but is what
i see correct (on a 1.8 system)?

If codec_ulaw and codec_gsm are both loaded, yes. These are built by 
default and auto loaded by default so they should be.

Correct.

Yes, there is no capability for video transcoding in any version of 
Asterisk.

Thanks for pointing out!

So in case my managers starts nagging about it, they have two options:
A) use hard/soft-clients with comparable codecs,
B) raise enough funds for implementing video-stream transcoding ;-)
