GO HERE VoIP Door Intercoms

[hbonath]

I have a client that has a phone-integrated door buzzer system.
These doors use external unlock mechanisms, however the doorbells themselves attach to their current Iwatsu phone system.
We are in the process of replacing their system with a hosted PBX, however we need to replace the door intercoms.
Can anyone recommend something that works with Asterisk/PiaF? Preferrably something that would dial a pre-determined number even possibly with a distinctive ring capability.
Could be Analog with ATA or PoE/SIP.
Thanks!

I personally use (well, used. Pressure washing with bleach caused its demise) a Viking E-50-SS. I was very happy with it, save for the somewhat quiet speaker. There was a thread about this not too long ago too. Can't find it though. It doesn't open doors, but it can come with a camera. Someone else in the other thread said that they bought one of the 2N Helios IP intercom units. Those are straight SIP and are NICE, but $$$$. I really wish I could find that other thread.

Valcom also makes an awesome sip door phone. It even has relays that can be used to activate other equipment like door locks, or lights.

Bogen ADP-1 ($140) and an analog terminal adaptor (Obi 100 - $40.00). Works fantastic. No Camera though.

 

[hbonath]

Awesome, thanks guys.
Now, understanding that they have Aastra 6737i's on site that will be called when the doorbell is pressed, as well as never have set something like this up - here are my thoughts, let me know if I'm on the right track:

Let's say I went with the Bogen ADP1, which looks like a nice sturdy unit, wired into an ATA.
I'm assuming that the unit itself is "dumb" and when the button is pressed the phone is taken "off-hook"
Would the best practice be to set up an Off-Hook Auto dial to call or intercom the phone at the reception area where the unlock button is, along with sending some sort of distinctive ring via Alert-Info, or maybe that would be the job of a ring group to set the distinctive ring for the Aastra...
Or does the Bogen have some other smarts that can be set, maybe it has an internal autodialer?

Right now, their Iwatsu phones play a "ding-dong" type doorbell sound, which I'm assuming I will not be able to replicate with a SIP/ATA type setup.
This is of course what they want, but as we all know, it's a difficult task when customers want an IP phone system and then want it to be EXACTLY like their old keyswitch system!

I appreciate the advice!

Hey guys, I'd like to *bump* this thread again, as I have since deployed this setup.
The way I've done it is as described above, and I used Alert-Info to change the ring cadence, not tone when a doorbell is pressed.

After having this in place, for a couple months, the customer is really unhappy with the way the phones ring with the cadence changed. They would like a differentiated ring tone instead.

The phone endpoints are Aastra 6737i and 6731i.

Is there a way to change ring tone, not cadence, on the Aastra platform via a SIP packet?
Or, perhaps have the phones register a second extension using Aastra scripts? (The ring tone can be changed in the config file on a per-extension basis)

Any creative ideas welcome!

 

[snarpatroid]

I might be missing the point here, but how I have my setup is for my doorbell to be allocated to a specific ring group then I set the <bellcore> option to whatever I want so I get a distinctive ring.

Have you tried to upload a new ringtone to the phones that sounds like a doorbell?

Have you tried to upload a new ringtone to the phones that sounds like a doorbell?

Unfortunately, you can't upload ring-tones/custom .WAV files to the Aastra 6737i/6731i. You can specify ring-tone by line key in aastra.cfg, [MAC].cfg, and/or 6737i.cfg/6731i.cfg.

As far as I know, you can only change the cadence (Bellcore option) and not the ring-tone via SIP. Someone else may know something I don't!

That's correct as far as I know as well. It seems that you *can* change ringtone on a per-line basis.
So what I was thinking is that if I configure a secondary extension on each phone in the ring group, then I would be able to ring the secondary extension which would have a different tone, say tone 4 or 5.
However I'm using the Aastra XML Scripts for all of these extensions, and am totally thinking that I can not do multiple extensions with the scripts.

So another thought I had was to write a dialplan function in extensions_custom.conf that would do an intercom to the group of extensions, play a .wav file, and hang up, but that's getting a bit wild - plus I am thinking that would then defeat the purpose of having a door phone if all it does is play the sound file.

I welcome any creative or wild and crazy solutions.

I'm currently using <bellcore-dr3> which is 3 short rings, but some of the people at this site are unable to differentiate that from a ringing phone. I've seen some of them pick up the phone and answer it at the reception desk unsure what to do... *face palm*

Depending on the building layout would a central ringer work, buy a cheap $40 sip phone have it ring and put a pickup button on each phone.

Thats interesting as I was just reading the release notes for the latest Aastra Firmware, and they now seem to allow you to play a ringtone when a BLF/Monitored extension rings(!) http://www.aastrausa.com/cps/rde/aa...P10_XML&dsproject=www-aastrausa-com&mtype=pdf

SIP version 3.3.1.5078

So what I'm thinking is that when a doorbell is pressed, it dials some dummy extension that is BLF monitored, then the phone also monitors those BLF's and plays a different ringtone. I'll have to lab this up but it could work.

 

[hbonath]

Nice work Sir!
Sounds like you've saved me some time, as I haven't had a chance to lab this up yet!!

Quick Question, if I wanted to monitor a "fake" BLF is that possible with some custom dialplan stuff or Virtual extension?
This site has 8 different doorbells that go to 8 different ring groups, and I would like to try to use this BLF thing to give distinct ring for each group.
I am thinking that instead of ring groups that get dialed when the doorbell is pressed, I would have it dial some dialplan extension that would trigger a BLF ring and therefore play the ring splash, without tying that BLF to an actual phone... am I nuts?

 

[hbonath]

I'm already using alert-info <Bellcore-dr3>
however Staff is complaining about how they can tell the difference between that and the phone ringing.
It sucks because I've spent all this time researching and installing all this stuff, only for the users to nitpick me to death, and send me on this wild goose chase to change the ringtone.

 

[TwigsUSAN]

Sometimes it's ok to say no you can't do that.

 

[ou812]

This may sound crazy, but is there a way to create a sip station account and have it register to a sip trunk account so now you can deal with routing a incoming trunk call to those phones.
Just a wild thought that pop into my head.

[TwigsUSAN]

Well, I have had to tell customers no on multiple occasions. Just explain to them that the technology wasn't necessarily made to do what they want. Especially of it wasn't part of the original agreement.
