Probably not.

I'm guessing this is for just a few calls at a time, correct? I'd
guess that rather than these quality issues being caused by cramped
bandwidth, they're actually being caused by latency issues.  Have you
ever checked the latency of the connection between your asterisk
server and your SIP/IAX endpoint? If it's really high (say 300ms+) or
if the latency is really erratic, you'll have quality issues.

You didn't mention whether you are doing traffic shaping on your
upstream connection, so I'll assume you're not.  That would be
something good to look into - with traffic shaping, you can prioritize
your VoIP traffic over all other types of network traffic.
