[VoIP] In-Band Signaling

[Greg Blakely]

I stumbled across an odd thing today while going through the trunk
groups that attach to the Siemens EWSD switch that I work on in my real
life --  a trunk group that goes to the MPLSMNDT12T toll tandem, and
it's set up for MF.  
 
I was pretty busy, but I'm almost certain that we don't actually have a
**live** MF trunk group going to Qwest, but it'd sure be cool if we did.
The portal number I have listed on ckts.info is served by the EWSD, so,
if I can get the MF trunks turned up without the need of a service
order, we may have some 'production' inband signaling for all of us to
listen to.
 
Probably not, though.  But, you never know
