<div class=Section1>
<p class=MsoNormal>All,<o:p></o:p></p>
<p class=MsoNormal>I have done research on VoIP for some time now. I’m a Cisco
certified Network Engineer however Telecom is not my strongest suit. I’ve
been a part of this mailing list for sometime but my delusions of grandeur in
migrating our 25 year old phone system to a new platform have been on the back
burner, until now. I have found my company is moving to a new
location(building) and this provides perfect opportunity.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Long story short, I’m very Linux savvy having no
problems compiling, building, making etc.. However getting connected to the
PSTN is puzzling me. My vocabulary is lacking and I need to call our provider
this week and get some circuits moved. So, my confusion….<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>(Current Setup)<o:p></o:p></p>
<p class=MsoNormal>We have a T1 coming into the building(FYI-Our Voice and Data
are on separate T’s) terminating at the Smart Jack. Then a cable from the
T card(SmartCard) to the channel bank. From the Channel bank lines are punched
down to the block. Then those ANALOG lines are fed into our Big hunking PBX
mounted on the wall and two (Looks to be Rj11) lines come from it into our VM
server.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Q&A..<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We are going to leave the telecom hardware behind.. I want
to replace it all with an Asterisk or Tribox solution.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I can tell you our current phone system can handle 7 phone
calls at a time:<o:p></o:p></p>
<p class=MsoNormal> Does this mean the T only has 7 channels provisioned
out of the 24 possible?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> Does a channel (In terms of the T1) = a port?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> How many phone calls can one TDM400 support
concurrently? (four ??)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> Would I be better off getting a Zapata T1 card and forgetting
the Channel bank all together(Use the digital signal)?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> Or Have a channel bank installed and use an
OpenSwitch12 solution working with the analog signal?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> If we go with a Zapata T1 card for the Asterisk server
would we be able to provision an analog phone line, for say a FAX machine from
it?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>(Further information)<o:p></o:p></p>
<p class=MsoNormal>Ultimately this is the FIRST of 3 offices that will be
migrated. This first office has 30 physical phones and currently no DID (Hoping
to change that as well) Once the second and third offices migrate(about the
same number of stations) we would connect the 3 Asterisk systems over the WAN
giving us free long distance between offices. The toughest challenge I foresee
is getting overhead intercom/paging to work(We must be able to hail our warehouse
staff over head), also Music on Hold… If I use Cisco 7940’s (SIP)
(Or the like) I’d like to integrate our phone extensions for a 3 offices
into the directory<o:p></o:p></p>
<p class=MsoNormal>Does this sound do-able?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
