P-Preferred Identity Header for BLA Accounts
The IP Phones support the BLA specification, draft-anil-sipping-bla-02, which
states that the P-Preferrred-Identity header (RFC3325) gets added to the INVITE
message to indicate the Caller-ID that is used for the call.
Note:
The P-Preferred-Identity for BLA accounts is also sent for hold/
unhold messages.
