There's no need to use ast_copy_string if the buffers are guaranteed to be the same length, which is the case for both structs.

To quote further from the Coding Guidelines:

{quote}
Don't use ast_copy_string (or any length-limited copy function) for copying fixed (known at compile time) strings into buffers, if the buffer is something that has been allocated in the function doing the copying. In that case, you know at the time you are writing the code whether the buffer is large enough for the fixed string or not, and if it's not, your code won't work anyway! Use strcpy() for this operation, or directly set the first two characters of the buffer if you are just trying to store a one character string in the buffer. If you are trying to 'empty' the buffer, just store a single NULL character ('\0') in the first byte of the buffer; nothing else is needed, and any other method is wasteful.
{quote}

While that's referring to a slightly different situation, we know that both the source and destination are the same length. There's no need to use ast_copy_string.
