VMSP Bridge
CFWD Bridge Mode
XFER Bridge Mode
Linksys Voice System Administration Guide
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.
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
Instructs the SPA9000 how to handle call transferring 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 SIP REFER method to the calling device to let it contact the transfer
target directly. The SPA9000 then drops out of the call completely. This
requires the calling device (the transferee) and the target device to
understand the SIP signaling involved and the operation permitted by
the underlying service providers. Note that the call legs with transferee
and the transfer target might be with different ITSP. The SPA400, for
instance, cannot handle this operation.
With bridging, the SPA9000 maintains two separate call legs throughout
the call: one with the transferred call and one with the transfer target.
The two call peers connect only with the SPA9000, while the SPA9000

This parameter has three possible values:
none —Do not bridge call transfer (use the normal REFER method)
all —Bridge all call transfer
all except same line—Bridge call transfer only if it is between 2 different
