A common approach to avoid delimiter issues in general is to store base64-encoded strings in Redis rather than the original strings. If whatever is reading from Redis can un-encode them, that pretty well solves the problem.

A review of the module's source appears to indicate that there is a hard limit of 3 substitution values when using this method.

Escaping the value, even by using $_s to eval a dynamic string, ends up with Kamailio itself apparently trying to parse the escape and breaking things further.
