<P><FONT SIZE=2>Hi,<BR>
<BR>
Are you getting four digits from the PSTN at site A?<BR>
<BR>
Perhaps there is no match to the 1008-1012 range and therefor the alias does not kick in.<BR>
<BR>

Subject: [cisco-voip] Call redirection using alias command in event of WANfailure [bcc][faked-from][html-rem]<BR>
<BR>
Hello List,<BR>
<BR>
<BR>
<BR>
I am looking to setup a call redirection for inbound DID survivability in a<BR>
office with remote VoIP gateway using the alias command, and previous testing<BR>
did not seem to work.<BR>
<BR>
<BR>
<BR>
I have office A with a PRI full of DIDs terminating at a 2821 and WAN<BR>
connection to Office B (head site) where the call Managers live. Office A<BR>
phones register to CM at office B. Office C also has a WAN to Office B and<BR>
registers its phones there. Office C gets its DIDs from the PRI at Office A.<BR>
This all works fine, but we want to eliminate any busy tones if WAN links die<BR>
during office hours. If office C loses its WAN, then calls will go to unity<BR>
from the CM at Office B or can be redirected from there, which is fine.<BR>
<BR>
<BR>
<BR>
Problem is, If Office A loses its WAN, SRST kicks in and they can still<BR>
receive calls, but then the DIDs for Office C go to busy. We want to redirect<BR>
these DID calls to another extension at Office A until the WAN comes back up,<BR>
so the calls can be answered by another user. Here is how we had it<BR>
configured (on the Office A 2821) and it did not seem to work. (1000 and 1002<BR>
are extensions at Office A, and 1008-1012 are extensions at Office C)<BR>

<BR>
alias 1 1012 to 1002<BR>
<BR>
<BR>
<BR>
<BR>
<BR>
Is there something else I am missing? Do I need to somehow tell the SRST<BR>
config something more about the inbound DIDs since it has lost connection to<BR>
CM?<BR>
<BR>
<BR>
<BR>
TIA,<BR>
