Don't have operational experience with XO, but can vouch for Asterisk interoperation with Level3. I have completed interop for Local Inbound and have it running in production. I am about to start interop for TollFree w/SIP termination and Voice termination (outbound) and don't expect any problems. Local inbound interop was achieved with Asterisk 1.4 behind OpenSBC, however it would also have worked fine without the SBC.
Voice quality is rock solid, shortcomings are the up front cost. There was nothing in interop that couldn't be addressed through extensions.conf As for problems, well as someone mentioned earlier, these large organisations can be slow and frustrating to deal with, however Level3 have jitter, packet loss and latency SLAs. I was comparing Level3 and XO for local inbound product last year and whilst XO was definitely cheaper for small to moderate call volumes, Level3 had better USA coverage and was cheaper for higher concurrent call volumes where they charge per megabit and per minute. I would be happy to talk further about my experience by email if anyone wishes.

When the service works it's fantastic. When you have a problem (QoS|billing|outage|etc...) you are SOL. Nothing atypical for XO however.
