[cisco-voip] Are there any telco guy out there?

[Chad Whitten]

we have had the same problem on calls forwarded from one telco (a local clec) 
to another (the incumbent rboc).  what we had was a number from the clec 
forwarded to a DID from the rboc.  horrible voice quality on those calls.  
its actually happened with two different clec's so I dont think its something 
to do with our voip system or the rboc system but just with the latency 
induced in the forwarding from one telco to another.
