correct. SIP. SIP also offers up additional details they can send down the line. i think you can use it in combination with PSALI, but i'm not sure it's required. from what i recall, they can send the main number and extension information down as well. 

definitely offers up advantages

I'm pretty sure that 911enable uses SIP trunks then routes them back to the local PSAP. But Good point.

as far as I know 911 does not understand area codes, each 911 tandem switch is programmed for a particular area code, so you can only opt out of local lines if the hq lines are going to the same CO/tandem switch. 

then again, if you have something like 911Enable, it interfaces directly into the 911 cloud and you can send 911 calls out from anywhere through your HQ trunks.

psali is the Database that PSAP's use to map your telephone number to physical address. 


up here it costs about $65 / month to have ~1000 numbers in the db. if you have it setup, then you can get away without having a POTS line at the location. But you have no SRST and no dialtone in the case of an outage. 


Most times Management doesnt want to spend ~2-3k for a router.... they figure 2-5 phones is not mission critical. All depends on your NEEDs.

oK, I'm dumb. what's a PS-ALI DB update??!! I have two other small locations, both with 3 phones. We put 2801s out there for SRST, but more importantly, for 911 calls. This was setup years ago in the 4.1 era.

how far away is the main site? are you concerned about 911 calls? Do you have to have telco lines coming in? 


911 could be fixed with a PS-ALI DB update. 


If you don't need telco lines and SRST, you could probably do without the router.

Need to connect another building into my fiber optic net. So fiber is already at this building. We will only have 3 phones there. 
I know there is a small 3560 (I think 8 ports POE) but what could I use for the router? The 2801s are just so big and probably overpowered for this scenario. 

Thanks anyone.
