codec_builtin: Use multiples of 20 for maximum_ms

Some providers require a multiple of 20 for the maxptime or fail to complete calls,
e.g. Vivo in Brazil. To increase compatibility, only multiples of 20 are now used.

Resolves: #260
(cherry picked from commit ca1ed84820f84416278f770f773aa1fa2b5efc03)
