| Can someone post a known working config for MGCP Fallback to H.323 SRST
using analog FXO ports and/or PRI. I am having a little trouble getting
the outbound inbound calls working once the phones failover. In
particular I need to see specific commands on Pots dial peers and what
actually needs to be there.
Not sure if I need incoming called number under each dial peer or a
separate dial peer to catch the incoming call leg, etc. Any help would
be appreciated.
Thanks,
Carlos

| Can you post your config or portion of it?
On the dial-peers pointing to analog fxs/fxo ports,
you need service mgcpapp (if 12.3.14T and higher) or
application mgcpapp. This command is not needed on the
dial-peer with PRI port. In Fallback mode the gateway
is operating in H323 mode so the dial-peers will look
like a H323 gateway, you may need translation
patterns, etc maybe depending on your call flow.
Globally, you need ccm-manager fallback-mgcp and the
following..
For cisco IOS® Software Release 12.3(13)T or
earlier:
R(config)#call application alternate default
For cisco IOS® Software Release 12.3(14)T or
later:
R(config)#application
R(config-app)#global
R(config-app-global)#service alternate Default

| Erick Thanks for the response. Yes this is IOS 12.3(11)T7 and I do have
the correct fallback commands as you described in your email. I think
my problem is that I have been congiguring all my Gateway MGCP for the
last year and converted the H.323 ones to MGCP as well. I just
remembered there ius one H.323 gateway left and when examining that
router I saw the following:
dial-peer voice 911 pots
destination-pattern 9911
progress_ind setup enable 3
progress_ind alert enable 8
progress_ind progress enable 8
progress_ind connect enable 8
direct-inward-dial
port 1/1/0
forward-digits all
My current MGCP fallback router has pots dial-peers that look like this
:
dial-peer voice 999001 pots
application mgcpapp
destination-pattern 9T
incoming called-number .
direct-inward-dial
port 0/0/1
I think I'm just missing some of the basics under these dial peers.

| Hi Carlos,
I used the following configuration guides available from
Cisco Online, with no problems. Just remember that this guides are for
IOS12.2.(11)T onwards and that the command "call appplication alternate
default" has changed to the following on IOS 12.3.14T onwards
application
==>global
==> service alternate dafault
Guides
======
1-) Configuring SRS Telephony and MGCP Gateway Fallback (
http://www.cisco.com/warp/public/78...cpfallback.html)
2-) MGCP Gateway Fallback Transition to Default H.323 Session Application (
http://www.cisco.com/en/US/tech/tk1...08012ecc6.shtml
)
I also had to use an Outbound Translation Rule because in our environment
users dial a "0" to obtain an outside line. More information about
translation rules can be found at,
You can find out more information about "Number Translation using Voice
Translation Profiles" from
http://www.cisco.com/en/US/tech/tk6...0803f818a.shtml
http://www.cisco.com/en/US/products.../>

Nevertheless, I have also inlcuded a working config for you.
Hope it helps,
