A method () for establishing a communication session between a caller device () and a called device () in a two-stage dialing protocol is provided. The method includes transmitting () at least one list of contacts and at least one list of index values to a communication server. Each index value of the at least one list of index values is associated with a corresponding contact from the at least one list of contacts. Further, the method includes initiating () a first-stage communication between a communication between the caller device and the communication server based communication server based on an input received at the caller device the caller device. Furthermore, the method includes transmitting () at least one set of characters of communication server based on a set of inputs received at the caller device and establishing () the communication session between the caller device and the called device based on the at least one set of characters.

Method and system for optimizing two-stage dialing

A method () for determining capability of a serving system for anchoring a call using an intelligent network protocol is provided. A communication network () includes a plurality of serving systems. Each serving system of the plurality of serving systems is associated with a unique identifier (ID). The method at a communication device () includes detecting () a movement of the communication device from a first serving system () to a second serving system () based on the unique ID of the first serving system and the unique ID of the second serving system. Further, the method includes accessing () a list that includes a mapping of the unique ID of each serving system with the intelligent network protocol capability of the serving system. Furthermore, the method includes determining (), based on the list, whether the second serving system supports the intelligent network protocol for anchoring a call.
