Claim:
1. A computer-implemented method for redirecting a call, comprising: receiving a first call request from a first user device via a first telephony service provider network to establish an off-net call with a second user device registered on a second telephony service provider network; determining that the first user device is associated with an account of the second telephony service provider network based on a communication identifier of the first user device included in the first call request; and sending a notification massage to the first user device indicating that the off-net call is able to be established as an on-net call over the second telephony service provider network: wherein determining that a first user associated with the first user device is a subscriber of the second telephony service provider network includes: extracting the communication identifier of the first user device from the first call request; searching a subscriber database based on the communication identifier; and determining that the first user device is associated with a telephony service account with the second telephony service provider network.
