The following notes and known limitations apply to the operation of B199 phones with IP Office systems.
The IP Office system's HTTP Redirection setting is only support for IP Office R11.1 FP2 SP4 and B199 phones running R1.0 FP6 or higher.
Phone register commands from system monitor are not applied to B199 phones.
B199 DES option cannot be disabled on a factory reset phone unless IP Office is acting as the DHCP server.
The B199 does not provide dial-pad for early media scenarios to enter the mid-call digits. Therefore, it cannot support early media calls where a user needs to input digits, for example for account code/authorization code entry or for input to an IVR
B199 phones do not support dual RTCP monitoring.
