[cisco-voip] sending 999 calls via the FXO in both CUCM and SRST mode

Thu Aug 23 23:20:41 EDT 2012

No, if the phone is registered with CUCM then the gateway has nothing to do with anything *until* CUCM sends a call to it. The phone does not magically know what gateway is the local gateway and cannot magically read gateways' dial peers. CUCM is the call... manager. So you need to configure CUCM to send the calls to the desired places, regardless of your gateway protocol.

Bottom line, yes it's not the cleanest solution. But it's kind of what you signed up for when trying to do non-centralized routing out of a centralized system. That is why centralized solutions like Emergency Responder or Enable 911 were invented.

That said, doing it the way you're trying to isn't *that* bad if you carefully consider the way device CSS and DN CSS combine. Personally, I do the non-centralized emergency route patterns in the device CSS, and the centralized non-emergency routes in the DN CSS. Using "local route group" probably makes it even easier but I am not familiar with that feature since I only recently migrated to a version that supports it.

Thanks for that Nate, But I was under the impression that when a phone even though regestered with the Centralized CUCM, still realizing that for the 999 pattern there is a local dial peer which is under the H323 control and therefore he doesnt need to go to the CM.

we have around 150 sites, which wil mean that we have to configure 150 RP on the CUCM for that. which is messy, veryyyy messy

Even if you were to manage to make the port be H.323, I'm not seeing what that would accomplish. You'd still need to do something in CUCM in order for CUCM to know to send the calls from certain phones to that specific H.323 gateway.

Scott,

we want not to get more hardware or providers on this.

I heard somewhere, that you can configure a Voice Gateway such that one interface is controlled by MGCP another is H323 and so on.

so if I can somehow control that FXO on H323 then that can use the local dial peers no matter what.

So the million dollar questions becomes how to have this one FXO interface controlled by an H323 in an MGCP gateway!!!!!!!!!

if you want an easier solution, use a sip e911 provider and let them route it.

otherwise yes, create a site_911 partition and add it to the site CSS with a 911 RP in that site_911 partion.

Hi all,

I have to configure an FXO line for 999 calls.

okay this works fine when i am in SRST mode and I have application global alternate default ON with

dial-peer voice 999 pots

description EMERGENCY

destination-pattern 999

port 0/1/0

forward-digits all

and for incoming calls

voice-port 0/1/0

echo-cancel coverage 64

cptone GB

timing hookflash-out 50

connection plar opx 61234

impedance complex2

where 61234 is an extension.

the only issue is when the CUCM comes back in that FXO re-registeres with CUCM as

dial-peer voice 999010 pots

preference 1

service MGCPAPP

port 0/1/0

again incoming calls wil work fine as I have an Attendent DN configured. but for the outgoing calls I only want it to use the local FXO

(for the emergency services to trunup at the right location)

I wonder if that can only be done in the CUCM as configuring local 999 route pattern and limiting the phones to use them in any case!!

we have alot of site and that will be alot of work on the CUCM.

isnt there a better way!!!!

thanks for the help

A
