Select “Minimize SIP message size” if SIP messages are getting too long in the
network. This setting allows headers of messages in abbreviated format.
Ensure that your Call Manager supports minimized SIP message.
The CS-700 supports several means to transport DTMF information entered
during a call to the far end. This setting should be consistent with the method
supported by the call manager.
The SIP standard defines the payload range for DTMF tones. Some call
managers do not accept all payload types, select the supported payload type in
this setting.
Lastly, some call managers require RFC 2543 for on-hold media. For these call
managers, change the Media on-hold message to that value.
