ATA question

[tnshurtm]

A difference in how Cisco and Shoretel handle analog phones confuses me.

Right now, with our Cisco system, we have a small device (ATA) that I plug into my network and it shows up as a device in the Cisco Call manager. I can assign a phone number to that device and plug an analog phone into the ATA and it works. The ip to analog happens at the ATA therefore, I can use any network jack as an analog phone jack as well.

THIS IS GREAT!!!!!!!

Now, as I am learning about the Shoretel system, I find that I have to have a special cable punched down to an analog block and have the analog lines dropped whereever I want an analog phone.

Is there a separate ATA device that you can use with the Shoretel system?

Thank you,

Not that I am aware of... What exactly is the device? Is it vendor neutral? Maybe you can make it work for analog across platforms.

It is actually a little Cisco box that registers with the Cisco call manager as a device/phone.

It is very handy. I don't know how I would get it to register with the Shoretel director though...

I wonder if it would see it as a SIP device:

SOFTWARE SPECIFICATIONS

Voice-over-IP (VoIP) Protocols

• SIP (RFC 2543)

• SCCP

You can purchase a little box from cortelco that makes a sip trunk into a analog trunk.

Mediatrix ATA's are certified with Shoretel now I believe.

Is there any reason why you can't just replace the whole thing with a Shoretel ip phone and be done with it?
shoretel ip phone has the analog functionality + it's "ip-mobile" like a ATA + you can assign phone number + DID to the phone.
This should take care of your problem, I hope.

That 'special cable' is an amphenol cable. They're under $10 at Graybar. You could also add a RJ11 patch panel.

The reason I can't use a phone is because they are fax machines and postage meters.

I would install a 2 port mediatrix as a sip/ATA device. I haven't checked if Mediatrix ATA's are available as a single port device.

[tnshurtm]

Would that mediatrix save trunk space as opposed to configuring a whole trunk with the analog cable?

1 Analog device = 5 Ip Phones = 5 SIP trunks.

So basically, for every DSP chip you allocate for SIP, you can have 5 SIP trunks.

[tnshurtm]

and that mediatrix device = SIP?

yes mediatrix = sip

The Cisco box is SIP as well
SIP is how it communicates over over the RJ45.

I guess my question is how to set up a SIP device. I am going to try to use the Cisco ones that I have. Therefore, I can put 5 of my analog devices on one trunk instead of 5 correct?
