They do allow for iLBC. From their FAQ page:

Codecs. Carriers with primarily business customers should 
use the G.711 codec when sending VoIP traffic to VoipJet. 
This ensures that all calls are of the highest sound 
quality and free from compression degradation. You've paid 
for VoipJet Tier 1 telco termination and G.711 lets you 
fully enjoy it. And don't forget some other codecs can add 
significantly to a call's end-to-end latency, too.

If you need to save bandwidth (admittedly very expensive 
in some parts of the world) then the iLBC codec bundled 
with Asterisk makes an excellent choice. It's free to use 
and takes one-fouth the bandwidth of G.711. Another 
important reason to try iLBC is if there is jitter and 
packet loss on your network's connection to us, because 
G.711 really needs ideal conditions to work well. Finally, 
GSM potentially uses even less bandwidth and CPU 
processing power than iLBC.
