Re: [Asterisk-Users] SIP Phones-Receptionist Setup

[Gregory Junker]

I went an nosed around the Bayonne site, and looked at their devel list 
archives....based on historical trends, that project looks dormant (it 
seems to be duplicating what Asterisk does already -- and better). Other 
projects it links to also look either dormant or missing.

I have seriously considered trying to track down the specifics of the 
Lucent ETR signalling, because I have a Partner key system I would like 
to use still. Yes, I absolutely could just dump Zap lines into the main 
system card, but then I lose the ability to signal into Asterisk (i.e. 
call transfers between the key phones and a remote VoIP user, etc). In 
short, it's really not meant to work that way and the solution comes up 
short on many levels. Getting * to speak ETR, however, is a completely 
different ballgame (although figuring out a powering scheme for the 
phones introduces another challenge).

Is there an open source key system, comparable to *?

If there isn't , I'd be happy to work on developing one. It is clear 
that the need still exists for such a user interface paradigm.


Bayonne is supposed to act as a key system, at least that's what was 
described on the web page. IMHO, it's probably a lot cheaper to re-use 
the old key system in tandem with Asterisk. A while ago, there was a 
discussion on this list about the feasilbility of re-using Toshiba key 
phone handsets with Asterisk. As it is, Toshiba has a Dialogic-style PCI 
card to support 16 digital handsets. Unfortunately, the cost of the card 
is >US$2500 - much more than buying a brand new key phone.

It would be pretty cool, if someone can reverse engineer the protocol(s) 
used by popular key phone systems. I think it's possible to use HFC in 
NT mode to drive those handsets. IIRC, most digital phones work along 
the lines of ISDN phones.

Cheers.
