There are really only two large companies that will do SS7 via SigTran and they
are Syniverse and Neustar (formerly TNSi / Verisign / Illuminet), They don't
really like to give out their pricing publicly so you have to sign an NDA to get
it, but I would budget about $1,000 per month to be safe. You pay for each ISUP
route as well so that price depends on how many routes you have.
Are you asking which carriers provide SS7 links or which ones will do the host
switch product?
