[VoiceOps] Mexico Orig and Term

Hello all, I need to provide orig and term in Mexico city. i can do orig no problem through the usual suspects, VI, DIDWW, VOX, but whats the best way to do term? we're not an "international carrier" and this is a very specific case for an enterprise customer. Any guidance would be great. If there is a Mexican Carrier on the list you can ping me off list. Thanks! Shri
