SPA9000 Field Reference Voice tab B Mailbox Manage URL VMSP Bridge CFWD Bridge Mode This parameter allows $USER, $PROXY, and $MBID macros, such as $USER@$PROXY, or $MBID@$PROXY. Default: blank Applies only if this line interface offers voice mail services. It specifies whether the SPA9000 should bridge the call from an external caller on the same or a different line interface. The choices are: None-Do not bridge external calls from any line interfaces All-Bridge external calls from any line interfaces except from the same line All+Self-Bridge external calls from any line interfaces including the same line NOTE: If the external call is also on this line interface, the SPA9000 does not attempt to bridge the call even if the value is All. If is WAN, must be yes for VMSP Bridging to function properly. Default: None Instructs the SPA9000 how to handle call forwarding of an external caller to another external number by a client station. The normal way of performing this operation is for the SPA9000 to send a (blind) SIP REFER to the calling device to let it contact the target number directly. It then drops out of the call completely. This requires the calling device to understand the SIP signaling involved and the operation permitted by the underlying service provider. The SPA400, for instance, cannot handle this operation. With bridging, the SPA9000 maintains two separate call legs throughout the call: one with the caller and one with the call forward target. The two call peers connect only with the SPA9000, while the SPA9000 acts as a proxy for the RTP packets exchanged between the two parties. This parameter has two possible values: None-Do not bridge forwarded calls (use the normal REFER method) All-Bridge all forwarded calls Default: None SPA9000 Voice System Administration Guide 259
