External Call Prefix - Exclude Emergency Services (999/101)

[aquaium79]

We have a system setup whereby a user has to add a number 9 prefix in order to make external calls to the number they are dialing. Now, the problem is when users dial Emergency Services such as 999 or 101, they are still having to add the 9 prefix, making it 9999 or 9101 which isn't great, especially in emergency situations.

How do we go about changing this so that users do not have to add the 9 prefix to certain numbers? Do we do it in bulk or would it have to be done for individual users?

Completely new to Cisco Unified CM Administration and will probably need step by step instructions, sorry.

Any help would be really appreciated!

How did you worked with your call route inside your CM ?? and what is the type and version of your call gateway ??

Hi.

On CUCM you can configure a route pattern 911 and one for 101.

If you strip 9 digit at gateway level, you need to configure a pots dial-peer for 911 and one for 101 with " forward-digit all" keyword in order to have a match for those destinations and avoid digit strip.

I know I posted this a while back but tried an emergency call and it didn't work. I didn't quite understand what you were asking me to do.

We currently have a system set up where a 9 has to be dialed to obtain an outside line. I'm guessing this is why calling 999 doesn't work because the system in omitting the first 9.

How can I set it up so that all other external numbers require a 9 to be dialed before hand except for emergency numbers?

Really would appreciate some help with this...

aquaium79,

Go to

1- CM administration page > Call route > Route hunt > route pattern - click find

2- take a snap shoot ( print screen ) for the result

3- upload the jpeg picture here as attachment, it will help understanding how your call route works.

I've attached an image file of our route patterns as requested.

Thanks,

Hi,

Associated device column in the above table which you uploaded shows that you have ( RL SCHOOL and RL NULL ) gateways. did you been ensure that RLSCHOOL device is working good ? there is a posibility that RLSCHOOL not working and thats uses have to dial 9999 which will forward them to RL NULL device.

chick your gateways and let us know how its going with you.

RLSCHOOL devices are working fine but it strips the 9 from external calls where users have to dial a 9 before making a call. I am guessing this is where the issue is and as users are dialling 999 it strips away the first 9 and the call is lost. IF users dialled 9999 I think it would work.

I can't even test this out because you can't just dial 999 without causing problems.

For your information the RLSCHOOL route list is linked to a RGSCHOOL route group which has "GBNP:PreDot" selected in "Discard Digits"

Hi,

You already have a route pattern matching 999 for emergency calls in a Emergency partition.

9 as access code is stripped only for call matching 9. route pattern.

You have to make sure tha Emergency partition is on every Calling Search Space associated to Phones or DNs.

Than you have to check on your gateway config if you are stripping leading 9 on your dialpeers (if gateway uses SIP or H323 as signaling protocol) and , in case, configure a specific dialpeer for 999 destination with forward-digits all keyword.

Please keep us informed

EmergencyPartiton is on one Calling Search Space because we do not want to allow all users to have the ability to dial emergency numbers. I have associated this Calling Search Space to the users/devices that we want to allow calls to emergency numbers.

When you say "...configure a specific dialpeer for 999 destination with forward-digits all keyword" how would I go about doing that?

I think that is what I need to do but I'm not sure how to do it. Like I said below we currently have the RLSCHOOL route list which is linked to a RGSCHOOL route group which has "GBNP:PreDot" selected in "Discard Digits".

[Carlo Poggiarelli]

Which singling protocol are you using between CUCM and Voice Gateway?

Le me know

Carlo

[aquaium79]

Sorry I'm not sure what you mean by signalling protocol... but I think the answer might be ISDN?

[Carlo Poggiarelli]

How did you configure your voice gateway?

H323, Sip ore MGCP?

Please let me know

Carlo

[aquaium79]

MGCP by the looks of it...

[Carlo Poggiarelli]

Ok,

can you please take a snapshot of Route List and route group configuration?

Thanks
