VMSP Bridge 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
Notes: 
  • 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 <PBX Network Interface> is WAN, <Force Media Proxy> must be yes for VMSP 
Bridging to function properly. 
The default is None. 
CFWD Bridge Mode Instructs the SPA9000 how to handle call forwarding of an external caller to another 
external number by a client station. This parameter was added in Release 5.1.
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
The default is None.
