[cisco-voip] Configure 3845 router for 911 call.

[Norton, Mike]

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.
