Is T38 forced on if you do this, or does it just enable the feature if it
sees it in a reinvite?  We have a bunch of fax lines w/ SPA2102 and then we
use Cisco routers as PRI-SIP gateways.  Some of the people use the lines for
phone too, so I need it to support T38 and regular g711 calls.  Right now we
just point the SPAs direct to the Cisco gateway and it works fine, but we
lose all accounting capability, voicemail, etc that we want/need.
