Call Control
3-30 AT Commands Reference Manual December 31, 2007
The following table shows the +CCFC parameters.
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.
