[asterisk-biz] Tier 1 SIP Providers?

[Dave Greenroom Creations]

Looking into how SIP providers work it seems like many of the companies 
are reselling SIP service from bigger providers.  Does it make sense 
that you then run into issues using these smaller companies since there 
are more HOPS added into the mix, since you need to access them, then 
they need to send you over to the main reseller?

The reason I'm asking is we always seem to run into outages and issues 
with most of the SIP providers we've used so far.  Either the quality 
isn't that great or we experience random downtime; so now I'm trying to 
figure out the most logical setup to have for our outbound calling system.

We have the flexibility of putting our servers anywhere; that being said 
would it make sense for us to find a tier 1 or high quality SIP, and 
somehow host our servers in the same datacenter as them?

Keep in mind we only do outbound voice broadcasting from sound files 
stored on our servers.  So we're not connecting our system to phone 
lines or using it for inbound calls.

Any insight on the best setup would be greatly appreciated.

Thanks,
Dave
