Under my experience with a few carriers, they seem to be mostly legacy telcos 
entering in SIP world with no enouch knowledge. In my opinion, carrier 
employees with long expertise in SS7 and so, are "forced" to learn SIP in a 
very short period of time. This is just because the carrier has bought some 
SIP softswitch to a big vendor, and wants to use it to offer IP connectivity 
for clients.

As a result, we get a telco with no real knowledge in SIP. Any report from 
clients are directly forwarded to the vendor (they have nothing to do with a 
well reported issue about SIP).

Basically the carrier has a black box and doesn't understand it. It the black 
box fails, then the clients have a big problem. This is, at least, my 
experience with "cool" carriers offering SIP.

Regards.
