SIP telephones can be integrated in a Basic MULAP. As a prerequisite, a system telephone (UP0 or HFA phone, for example) must have been defined as the first member of the Basic MULAP.

Remarques:

• No programming of MULAP keys is possible for SIP phones.
• No features can be activated or deactivated via codes.
• Specific display messages of the Basic MULAP are not supported.
