Question

Why do I receive the same FID [FID:9223372036854775807] value for all API responses when using Kannel?

Answer

By default, the Kannel configuration sets the FID value to an integer. However, the Vonage message ID values are too large to be considered integers. As a result, the Kannel logs always return the same FID value [FID:9223372036854775807]. This value (9223372036854775807) is the largest possible integer value that can be set on a 64-bit system.

Removing the "msg-id-type" from the Kannel config will reconfigure the FID value to a string. This will help display properly the value for the message-id in the Kannel logs.
