Having techs trained on Asterisk is not something that would be profitable for anyone, unless it is their sole niche play. I do know of a few "VOIP" companies that would do something similar to what you want, but would be rather expensive.

The best advice I can give you is find a solid provider who has a great track record for network and facility uptime (no company-wide network outages recently, no history of recurring power outages, etc.). There are definitely a nice selection in the industry, but you may want to do some actual homework on them.

Additionally, voice stuff gives some other unique challenges in provider selection. Will you ever want to get your own PRI lines connected directly to your systems? If you are not having lines connected directly, and your phone service is via VOIP figure out where your provider is located and try to plan your hosting accordingly.

If I was looking for a provider for a full-blown VoIP solution I would probably look for the following:

1) Quality, redundant network. Strong track record of network availability.
2) Quality facilities - tour them. Ensure things are n+1, proper facility access control, good cabling standards, etc.
3) Carrier neutral facility with many voice carriers on-net for cross-connect ability. This generally narrows my choices down to providers located in facilities like Equinix, NOTA, 25 broad, the Westin building, Infomart, etc.
4) On-staff tech's who can execute instructions quickly and accurately - not simply read off of a script (this rules out the remote-hands techs for ALL of the above facilities - so a reseller is needed)

After this, I would contract with one of many VoIP consultancy companies to set things up properly. You can do lots of fun things with failover and the like. These guys you would have design and run your Asterisk (or whatever) setup, and they would be who you call if it breaks - unless there is a full-blown power or network outage.

This is coming from someone who does manage a few Asterisk servers for company use. They have been very solid, but they do pose very unique requirements most hosting companies could not in good faith say they could "fully manage" for you - myself included.

Good luck!
