[Users] Sip Provider

Hello Everyone, I have finally got my sip router up and its running well, tested it to be true -thus far - with asterisk backend w/PSTN. Now, i want to start offering services, but only have one pstn channel. I was hoping that someone could advice me on a service provider that is willing to allow me to route calls to their sip router for a (monthly) fee, and if this is possible so I can offer services to users without being limited to a single channel and then I can see how sip simulatenous calls really perform? Advice? How much is fee for this type of situation to me (approximately range)? Please can some-1 provide me with recommendations providers? I need this for me betterment soon. Help? jwshel _________________________________________________________________ All-in-one security and maintenance for your PC.
