Technical Examples
  1. Methods and systems for providing wide-band voice service via a telecommunications switch are described herein. A call can be initiated from a wide-band telecommunications device (e.g., an IP telephone) to another telecommunications device through a gateway (e.g., an IP gateway) associated with one or more telecommunications networks, such as, for example, a WAN, LAN and/or PSTN. One or more digital signals (e.g., 4 or fewer DS0s) can then be reserved for the call, if a telecommunications switch (e.g., a class 5 circuit switch, 5ESS®, etc.) associated with one or more of the telecommunications networks determines that at least one timeslot is available to permit a transfer of the call to the other telecommunications device. Thereafter, a wide-band signal converted from the digital signal carrying the call from the gateway to the other telecommunications device can be passed over a telecommunications interface, such as a GR-303 connection, as determined by the telecommunications switch to the other telecommunications device.
