asterisk users - Jan 2010 - Do any providers support speex codec?

Do any providers support speex codec?

I just searched for a while and couldn't find anything.

I'm looking for both SIP vendors (such as galaxyvoice) and IAX / IAX2
vendors (such as voipjet).

I'm looking for a company that would be cheap for low-volume use.

Thanks,
