<P class=MsoPlainText>I did a similar setup “though I were not responsible for
the CVP part” but we fallback to a local CME-SRST on the router that have the
VXML script…we have a VOIP dial-peer pointing to the CVP when the WAN link is
down another dial-peer takes over after the SIP message timer experies…we have
the CallManager and CVP at the HQ and this setup is at the remote
site.<o:p></o:p></P>

<P class=MsoPlainText>> Hi,<o:p></o:p></P>
<P class=MsoPlainText>><o:p> </o:p></P>
<P class=MsoPlainText>> We're planning using a VXML script for incoming
PSTN calls, to play an <o:p></o:p></P>
<P class=MsoPlainText>> announcement and make a transfer to a specific IP
Phone in a branch. But, <o:p></o:p></P>
<P class=MsoPlainText>> when the WAN link is down, calls are dropped with
the default system error <o:p></o:p></P>
<P class=MsoPlainText>> message. (critical_error.wav) We need to add
survivability to this call <o:p></o:p></P>
<P class=MsoPlainText>> flow, ie. if the vxml server is not reachable, it
should bypass the script <o:p></o:p></P>
<P class=MsoPlainText>> and directly forward to call to the IP phone
specified.<o:p></o:p></P>
<P class=MsoPlainText>><o:p> </o:p></P>
<P class=MsoPlainText>> CVP config guide says the following:<o:p></o:p></P>
<P class=MsoPlainText>><o:p> </o:p></P>
<P class=MsoPlainText>> "On a Unified CVP Standalone call flow model, no
special survivability <o:p></o:p></P>
<P class=MsoPlainText>> dial-peer needs to be created. Survivability will
automatically be invoked <o:p></o:p></P>
<P class=MsoPlainText>> by the Unified CVP Standalone script if the
"survive" service exists."<o:p></o:p></P>
<P class=MsoPlainText>><o:p> </o:p></P>

<P class=MsoPlainText>><o:p> </o:p></P>
<P class=MsoPlainText>> But, survivability script doesn't seem to invoke
when a call is placed <o:p></o:p></P>
<P class=MsoPlainText>> when WAN link is down. So, again the system error
message is played and <o:p></o:p></P>
<P class=MsoPlainText>> the call is dropped.<o:p></o:p></P>
<P class=MsoPlainText>><o:p> </o:p></P>
<P class=MsoPlainText>> Does anyone have an experience with survivability
in a similar scenario?<o:p></o:p></P>
