Hi List; Asterisk does not have any kind of cards that can work with it to be used with Digital Phones (digital phones differ than analoge phone and differ than IP Phones). Anyone can advise about this as I did not find this on Diguim Regards Bilal Ghayad __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

What brand of digital phones, I think I read some time ago that someone was doing something with Nortel phones but I seem to remember the cost of the phone meant...better to toss the handsets and buy new sip handset.

You can use something like this which supposedly works well and is easy to configure. Costs about $120 per port full retail and works with all sort of phones including Nortel. http://www.citel.com/Products/Portico.asp -----Original Message----- From: Dean Collins [mailto:Dean@cognation.net] Sent: Tuesday, May 01, 2007 4:56 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: RE: [asterisk-users] Digital Phones What brand of digital phones, I think I read some time ago that someone was doing something with Nortel phones but I seem to remember the cost of the phone meant...better to toss the handsets and buy new sip handset.

You can also look at adsi phones, they should work well with a channel bank. Aastra makes some quite nice ADSI phones. They are not digital but can do a lot that digital phones could.

I have had poor experience with them and doubt I would try it again without seeing many improvements listed in their firmware releases. Just to clarify, I had loud bursts of static when first picking up or originating a call, phones resetting for no reason, regular interval popping sounds. Citel fixed the popping sound by replacing one of the gateways but the other issues were never fixed. Also, the phones did not act the way I would have liked. When dialing, only a beep was heard, not actual DTMF and stutter dialtone MWI could not be disabled even though the phone I used had a MWI light and LCD display showed messages.

Thanks for the "heads up". -Stephen-
Hi; Well, I understood now that Nortel has some digital phones that can be used with astrisk, but the question: what are the card models that should be installed on Asterisk server? Digium? What these models? Regards Bilal Ghayad ____________________________________________________________________________________ Bored stiff? Loosen up...

Can you connect existing Nortel system to Asterisk through fxs/fxo? That way one could use existing infrastructure for few old phones and Asterisk for new phones and all good things which come with it?> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com > [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of > Eric "ManxPower" Wieling > Sent: Wednesday, May 09, 2007 1:28 PM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: Re: [asterisk-users] Re: RE: Digital Phones > > bilal ghayyad wrote: > > Hi; > > > > Well, I understood now that Nortel has some digital phones > that can be > > used with astrisk, but the > > question: what are the card models that should be installed on > > Asterisk server?

Hi List; As I know from AVAYA (I am AVAYA certified) that digital phones are connected to digital cards and it does not go through ethernet switches at all, digital phones should be independent on the ethernet network, so if the network down, these phones will start working, it will be totally isolated from the data traffic. So, how that come the digital phones does not need a card for it? Also, how it will use ethernet switches! It does not work with IP Packets. Any one can advise.

We use the Handset Gateways from Citel. They convert SIP to Digital Handsets, so there is no hardware to add to the server and you can still use your 2-wire phone lines. -- -- Steven http://www.glimasoutheast.org "bilal ghayyad" <bilmar_gh@yahoo.com> wrote in message news:574635.85598.qm@web54603.mail.re2.yahoo.com...
