Techniques for retrieving a voicemail pilot number from a telecommunications network node

A non-transitory computer-readable storage medium that stores instructions to be executed by at least one processor,

• wherein the instructions cause a Telephony Application Server (TAS) to perform a method for depositing or retrieving a voicemail message without needing to issue an SS7 query for a voicemail pilot number,
• the method comprising:
• facilitating registration of a user equipment (UE),
• wherein the UE is associated with a subscriber to a telecommunications network;
• sending a request for a voicemail pilot number of the subscriber,
• wherein the request is based on Diameter protocol and includes an attribute-value pair (AVP);
• obtaining the voicemail pilot number at the TAS,
• wherein the voicemail pilot number is also available to the TAS, in response to an SS7 query, from a voicemail server;
• receiving a message for a voicemail service by the UE of the subscriber;
• retrieving the voicemail pilot number of the TAS in lieu of issuing the SS7 query to obtain the voicemail pilot number from the voicemail server;
• and
• enabling the subscriber to deposit or retrieve the voicemail message based on the voicemail pilot number retrieved from the TAS.

A system for retrieving a voicemail pilot number, the system comprising:

• one or more memories of a telecommunications network that stores instructions for depositing or retrieving voicemail messages and subscriber information including a voicemail pilot number for a subscriber to the telecommunications network,
• wherein the subscriber information is stored at a first telecommunications node;
• and
• one or more processors of the telecommunications network configured to execute the instructions stored on the one or more memories in response to an indication that a change in the voicemail pilot number was detected,
• wherein the change in the voicemail pilot number was detected by a second telecommunications node different from the first telecommunications node, and
• wherein execution of the instructions cause the system to:
• update the one or more memories to reflect the changed voicemail pilot number,
• wherein the changed voicemail pilot number is also available from a server by issuing an SS7 query for the server;
• receive a message to deposit or retrieve a voicemail message by the subscriber;
• and
• retrieve the changed voicemail pilot number stored in the one or more memories instead of issuing the SS7 query to obtain the changed voicemail pilot number from the server to thereby enable the subscriber to deposit or retrieve the voicemail message based on the voicemail pilot number retrieved from the one or more memories.
