Don't they have G.723.1 support? If not, that's a sad omission. Quite a 
few people need that, and only the Digium card has been able to offer it 
in a properly licenced manner.

There is no practical way to licence the patents for GSM-EFR, AMR -NB or 
AMR-WB for small to medium volume use. Sangoma get their licencing 
through the silicon they use. Same for Digium with their G.729 + G.723.1 
card licencing. Licencing through the silicon also gets G.729 patent 
licencing at much lower prices than the way Digium, Freeswitch and 
Howler need to licence the same patents for their purely software 
products. Its all rather messy, really.
