PREFIX followed by BLF fails when using handset
When activating a feature using the PREFIX key followed by the BLF key, the operation fails if the action is initiated by picking up the handset.
For example:
- Configure a PREFIX key with value *80 (voicecall feature code) and a BLF key for extension XXX.
- Pickup handset, press PREFIX key followed by BLF key.
- Expected result: voicecall (intercom) is made to extension XXX.
- Actual result: the *80 feature code is dropped, call is made to extension XXX instead.
Workaround:
- Press PREFIX key followed by BLF key, then pick up handset.
