The default value is 20.
Note: The parameter must be a multiple of 5, for example, 5, 10, 15 and so
on. If not, the module of 5 will be ignored.
Note: A forward-to phone <number> (and the optional fields <type>, <subaddr> and <satype>) are tied
to a <reason> and a <class>. This means that there can be a different <number> for the same <reason>
because of a different <class>. When registering without mentioning a <class>, <class>=7 is selected.
A <number> field is mandatory when registering (<mode>=3) and it is irrelevant (ignored) in all other
<mode>s.
