Remote service identifier

A device, comprising:

• a memory to store a plurality of instructions;
• and
• a processor configured to execute instructions in the memory to:
• receive at least one signaling protocol message from a voice over Internet Protocol (VoIP) call;
• identify a From value of the at least one signaling protocol message, wherein the From value includes at least one symbol;
• convert each symbol of the From value to a corresponding American Standard Code for Information Exchange (ASCII) decimal value;
• identify a To value of the at least one signaling protocol message, wherein the To value includes at least one symbol;
• convert each symbol of the To value to a corresponding ASCII decimal value;
• compare the ASCII decimal value of the From value to the ASCII decimal value of the To value to determine a larger integer and a smaller integer;
• and concatenate the larger integer and the smaller integer to form a remote service identifier based on a predetermined sequence.

A non-transitory computer-readable medium, including instructions executable by at least one processor, the computer-readable medium comprising one or more instructions for causing a processor to:

• identify a call origin associated with a voice over Internet Protocol (VoIP) call for more than two parties;
• determine at least one branch sub-key and a primary call key based on the call origin;
• determine a call tree based on the at least one branch sub-key and the primary call key;
• identify remote service identifiers (IDs) based on the call tree, wherein each remote service ID identifies a VoIP call based on a hash function conversion of a From value and a To value associated with a signaling pair for each branch of the call tree;
• identify a bounded time for a VoIP call;
• identify that each symbol of the To value and each symbol of the From value have been converted to corresponding ASCII decimal values;
• identify that the ASCII decimal value of the From value and the ASCII decimal value of the To value have been compared to determine a larger integer and a smaller integer;
• identify a predetermined sequence in which the larger integer and the smaller integer have been concatenated to form the remote service IDs;
• extract Session Initiation Protocol (SIP) messages based on the remote service IDs and the bounded time;
• and determine call flow based on SIP messages and time stamps associated with the SIP messages.
