Phone number verification method and system
Verifying an association between a phone number provisioned by a voice network and a phone device is useful on a synthetic communication network that reuses the phone number to transmit text and other media over a data network between devices registered on the synthesized network. Upon receiving a request to add a phone device registered with a voice network to the synthesized network, the phone number is presumed to be unconfirmed on the synthesized network. A verification message addressed to the phone device is transmitted through a data channel within the voice network. If the phone number is associated with the device, the message returns to the phone device over the data channel. If the message is received by the phone device, the phone number is confirmed as associated with the phone device, and the synthetic network authorizes communication between the device and other devices registered on the synthetic network. |

System and method for dynamic call-progress analysis and call processing
A telephony application such as an interactive voice response (“IVR”) needs to identify quickly the nature of the call (e.g., whether it is a person or machine answering a call) in order to initiate an appropriate voice application. Conventionally, the call stream is sent to a call-progress analyzer (“CPA”) for analysis. Once a result is reached, the call stream is redirected to a call processing unit running the IVR according to the analyzed result. The present scheme feeds the call stream simultaneous to both the CPA and the IVR. The CPA is allowed to continue analyzing and outputting a series of analysis results until a predetermined result appears. In the meantime, the IVR can dynamically adapt itself to the latest analysis results and interact with the call with a minimum of delay. |
