Useful Tips
The following information should be noted:
• If the phone has only the H.323 protocol enabled, it cannot be used to
answer SIP calls.
• If the phone has only the SIP protocol enabled, it cannot be used to answer
H.323 calls.
• If both SIP and H.323 protocols are disabled by mistake, the phone will
continue to work as a SIP-only phone; however, the phone is not
registered (you are able to send and receive SIP URL calls).
• The protocol that is used to place a call is stored in the placed call list of the
user's phone.
• The protocol to be used when placing a call from the user's local contact
directory is unspecified by default. The user can select SIP or H.323.
• The protocol that is used when placing a call from the user's corporate
directory depends on the order of the attributes in the corporate directory.
If only SIP_address is defined, then the SIP protocol is used. If only
H323_address is defined, then the H.323 protocol is used. If both are
defined, then the one that is defined first is used. For example, if
dir.corp.attribute.4.type is SIP_address and
