Outbound Calling

SIP Affinity provides complete outbound dialing services for global calling including domestic, international, E911, directory assistance and toll free dialing. CallerID is passed on all domestic calls and most international calls.

Our standard rates are low enough to be considered "wholesale" by many competitive providers. Yet quality, not cost, is our top priority. We only route calls via tier1 global networks via direct routes even when significantly cheaper alternatives may exist. Our view is low cost without reliability is not of value to our clients.


Our network is capable of supporting thousands of simultaneous calls. The only practical limit is your available bandwidth for call transport.


Our primary gateway is located in New York. Due to the quality of our Internet network we are able to provide premium low latency service from this location for clients the throughout U.S.A. and Europe. We also offer California and Texas gateways for silver accounts and higher (minimum $500/mo. in billable services). A Miami gateway is also available for gold accounts based in South America.SIP Accounts
