Everything is done in the CUCM.

Pots are configured with MGCP.

Create New Partition. (site Name)
Assign 911 Route for site A to Site Partition 1
Assign 911 Route for Site B to Site Partition 1
Assign all other Routes to both Partitions.

Only 911 calls are treated different per site - if you do not take phones 
between sites, you won't have a problem. Two POTS lines per site is correct.

I don't think I missed anything, it's not hard to accomplish the separate 911 
calls between PSAPS.

Subject: Re: [cisco-voip] Configure 3845 router for 911 calls.


Let me rephrase the questions with more understanding update after I talk to 
Mike and few other people.



We have 2 locations. one is main building were everything reside and the second 
 building is remote building shared with someone else.

About 50 people reside at  the secondary remote location. This people use main 
locations CUCM over the WAN for calling. Remote location is about 25 minutes 
from main building.



So if these people at remote location call 911, emergency responder will see 
main building location not remote location where the call is residing.

Therefore we are tasked to put together plan to give users option to be able to 
call 911 and show their true locations.



We are forced to find spare 3845 router to configure for this users for 911 
call. below is what we have.

ordered 2 POT Lines,

have 3845 router

We have both FOX and FXS modules for POT Lines.

Amphenol Cable to connect to FOX and 110 block.

CUCM version: 11.0



The reason we ordered 2 POT lines instead of circuit is because they are cheap. 
Circuit cost about $500 a month while POT line cost about $40 a line. Since 
this router is only used for 911 call we don't want to spend that much money.



The question, has any one configured router for 911 and have basic config that 
I can use for my config. Since I haven't done voice gateway configuration 
before, I just need help with this.



Any help is greatly appreciated.



Thanks

Hamu

For the IP phones to be usable during WAN outage, you need something they can 
register to. E.g. SRST or CME on the router, or else a CUCM server on-site.



The config you posted shows that this router already has T1 lines. You can send 
911 calls to T1 lines, I don't understand why you want to add analog POTS lines 
if you already have T1s.



If you want more suggestions then perhaps take this conversation back on to the 
mailing list, others besides me might be able to give you ideas.

Thank you Mike for following up!!



I Just clarified with person who gave me that project to put it together. That 
person was not really familiar with voice staff just mentioned analog phones. 
There is no analog phones here.  These users have 7942 IP phones and the idea 
was to user POT lines to call out to 911 if WAN connect down at the site. The 
idea was, since these users are in some else's building, we need to find out 
how to make them call out to 911 if WAN connection is down. Since I am not 100% 
sure of how we can achieve this. I am ok with your suggestion how to achieve 
this.



ordered 2 POT Lines,

have 3845 router

We have both FOX and FXS modules

Amphenol Cable.



thanks

Hamu

Hi Hamu, I don't fully understand your call flow. POTS lines would normally 
connect to an FXO card. In that case, the easiest way to handle incoming calls 
is to do "connection plar xxxx" on the voice-port, where xxxx is the extension 
number where you want to send the calls. But since you mention analog phones 
then it is not clear to me exactly what you are trying to do.



Maybe take the conversation back to the mail list and give more explanation of 
the call flow, might be able to get more help that way.

Thank you very much Mike. I really appreciate your help.

As I mentioned it before, These employees are residing in someone else's 
building and using CUCM across WAN. The reason behind trying to use POT Lines 
is, If WAN is done these employee will be able to use POT Lines from Analog 
phones to call out.



One question is, if you can share command to setting how to send 911 calls to 
reception or security desk.



I really appreciate your input and advise.



Thanks

Hamu

Currently your config will send the 911 calls out the "Local" T1. Once you have 
the POTS lines added, you will need to put your POTS ports into their own trunk 
group and direct your outgoing dial-peers to the new trunk group instead of 
"Local."



You should do something with inbound calls that come in on the POTS lines. E.g. 
if 911 calls you back, at bare minimum you should send the call to reception or 
security desk.



For POTS lines you need an FXO card, not an FXS card. FXO is for connecting to 
telco Offices, FXS is for connecting to analog telephone Sets. So FXS will not 
do what you need.



You don't have any SRST configured. Is your CUCM on-site? If CUCM is across the 
WAN then you need to have something on-site that phones can register to when 
the WAN is down (e.g. SRST, CME).



I don't understand why you need the POTS lines? Why not send 911 calls out one 
of the T1s that this router already has?

Hi Everyone,



I need help with this configuration for 911 only.



back ground history, our company bought another company few years back. After 
about 6 months, the deal fail apart. Within that 6 months employees moved 
around to different building mixed. When separation started, leaders negotiated 
so that we still provide professional service to the company that is separating 
from us for 3 years. In that 2 years, all the assets and employees need to be 
separated. There are about 50 employee of ours located in the building of the 
company that is in the process of separating from us.  We are in the process of 
separated them from this company system but in the same building. We had done 
all separation form phones to email server and etc. while in the process of 
separating this employee we have run into issue with 911 if the site loose WAN 
connection. I was tasked to figure out this. I am just wondering if anyone has 
done this and help me.



below is the router I am try to configure.

3845 with EVM-HD-8FXS/DID module

ordered Amphenol cable to connect to 110 block

ordered 2 POT Lines



I need help configuring this router for 911 call. I have attached the config I 
have and I am just wondering if I am missing anything. I haven't don't this 
kind of configuration before and I need guidance.



Thank you very much!!
