911 from remote IP phones.

[Philbert221]

Hi all,
We want to install a BCM50 in one of a customer's 2 locations. In the second location across town we want to install 5 2004 IP phones working across a point to point T1 back to the main site.
The question has arisen as to 911 emergency calls from the IP phones and making the response center caller-id see the remote location instead of the main site.
My question is, how can we accomplish this in cost effective manner. Ideally is there a way we can program the BCM50 to display a different 911 address based on the originating extension (highly unlikely I know)? Is there a device we can install on the remote network that has a POTS line hooked to it that will respond to 911 calls originating from the IP phones? Or any other method that anyone can think of.
Thanks in advance.

Install a POTS line at the office and hook up a telephone... I don't think any other option is available.

Activate an analog line with keycode at the remote site and have an analog line installed and thru destination code program 911 to route out the analog line.

Hi cook1082, not sure what you mean by " Activate an analog line with keycode at the remote site". How do I do this? There will not be a BCM at the remote location, just IP extensions running off BCM at main site.

As nstanto said, the POTS line/red phone is the easiest solution. Otherwise, you'd need a separate system or some type of gateway that you can connect an analog trunk to and route 911 calls that originate from the remote site out that trunk via VOIP. Not a very easy thing to do on the BCM platform.

 

[Philbert221]

I've already suggested the separate phone with analog line but it didn't fly with the customer. My next thought is to install an extra analog line at the main site and dedicate it to the remote site for their needs through whatever routing programming that is necessary. The only question would be whether or not the E911 people can modify their database to reflect a different address other than the service address.

 

[cook1082]

Call phone co. and order analog line for remote site.Get key code for BCM 50 to activate the analog trunks in the 50.Program 911 in destination codes, absorb I think none,route 003 use line 61.

 

[Philbert221]

Thanks for the responses, cook1082 I'm still confused as to how I install an analog line at remote site, enable keycode at main site and make them interface with each other.

 

[cook1082]

No put analog trunk key in at remote site so the line is installed into the bcm 50 remote site.And the call is made from the remote site to 911.It sends the call id of the remote site.From the remote site.Its all done in routing.

 

[Philbert221]

As I have mentioned in previous posts, there will not be a BCM system at remote site. Just IP extensions running off single system at main site.

These are your options as I see it:

1. Have a dedicated analog phone line with 1 or many analog phones at the remote location as previously mentioned. This might be a good idea anyway in case the IP phones are down due to network problems, etc. If the link is down and someone needs to dial 911 what are they going to use?

2. Contact the telco and see if they can change the 911 ALI information (on a new analog line that appears on the IP sets, via routing, etc) to reflect the remote location's address. I have no idea if this can be done (I doubt it) and it may depend on the telco. This will not be a BCM change as the ALI information is provided by the telco directly when a 911 call is placed (along with the ANI of course).

3. Install another BCM at the second site and do as cook1082 has suggested.

If it was me, I would just install a POTS line at the remote site and have the Telco block all calling except 911 calls. Bridge a few 500 set's on the line so people can use them for 911. put a lable on every phone saying to use the special 500 phones for 911. Like gentech said, what will you do if the network goes down?

 

[lugerlover]

how about when we dial out we have the remotes dial 8...not 9...then set up a route so when they diall 8911 we dial local pd/dispatch center

 

[lugerlover]

this is what i have to do on most of my t1..they had no 911 options

The best solution is an SRG50 with 1-2 local analog lines at the remote site. If you cannot afford that, then you can put an FXO gateway into your router at the remote site and add H323 trunks to your M1. Setup the router to be a remote gateway endpoint registered to the gatekeeper at the main office. Lastly configure the zone dialplan so that 911 calls from these sets use an H323 trunk and the gatekeeper sends them to the cisco router with FXO VWIC and POTS lines. This will work but will not be supported. You also have to worry about configuring dial-peers, etc. on the cisco router. Messy, but it does work.

Why would you be opposed to installing an SRG50. It really is not very expensive, especially when compared to adding an FXO VWIC and the extra complexity that will create.

Good Luck

SRG 50 would be a good answer, but from the original post it doesn't sound like there is a CS1000 in the picture anywhere.

 

[Philbert221]

So I have a new hardware solution from my equipment provider. It's a Quintum AS200 that uses IP trunking to the BCM50 and routes outbound calls through a FX0 port. Anybody with any experience with this device?
