[cisco-voip] Single button ARD

[Matthew Huff]

Here is a full example of what I need.

Two users, named Steve & Joe each with a 8861 SIP phone on CUCM 14.x

Steve has a prime-dn of 6000
Joe has a prime-dn of 6001

On Steve’s phone he has two extra buttons:

Speed Dial,               labeled [TO JOE],       which dials 7001
Directory Number, labeled [ FROM JOE] which has a DN of 7000

On Joe’s phone, he has two extra buttons:

Speed Dial,               labeled [TO STEVE],       which dials 7000
Directory Number, labeled [ FROM STEVE] which has a DN of 7001

That is easy and works fine.


But I need it to be single buttons:

On Steve’s phone
Labeled [JOE], which dials JOE and receives calls from JOE when he presses his [STEVE] button

One Joe’s phone
Labeled [STEVE], which dials Steve and receives call from Steve when he presses his [JOE] button


I have this working on SCCP phones in Call Mnager Express and is very standard in a trading environment. Anyone have any ideas?

That is exactly what I’m not trying to do. Everytime I mention PLAR or ARD those are the articles I’m referred to and are not helpful. That example and others are for courtesy phones, hotlines, etc..

What I need to do is when a dedicated T1 channel on the voice gateway (IOS 2800) goes off-hook it routes to a DN on the phone. When the same DN is picked up, it dials a number that routes back to the same channel on the voice gateway.

I can do this with two buttons (one being a speed dial, and the other being a DN), but I need this to be a single button. Someone could have 20 different ring downs on the same phone device.

What are your gateways built with, MGCP, H323, SIP? What version of call manager are you working on?

Ringdowns for call managers are built using CSSs, Partitions and a Null Translation pattern.

Here is a good article on it: https://www.networkcomputing.com/networking/using-cucm-configure-plar-phones

I’m trying to setup a button on people’s phone where they will get inbound calls like a (DN) when voice-port goes off-hook on our gateway (connection plar xxxx). When the button is pressed on any phone, it should do the same thing, take the channel off hook on the voice gateway.

All the example’s I’ve seen are for doing PLAR when the phone goes offhook or the “new call button” is pressed, but not a separate line.

I’ve done this in the past with CME like:


voice-port 0/3/1:0
define Tx-bits idle 1111
define Tx-bits seize 0000
define Rx-bits idle 1111
define Rx-bits seize 0000
no vad
no comfort-noise
connection plar B100

ephone-dn  32
number B100
trunk B101
