How do I make a FXS -SCCP line non-private CUCM 8.6.2.21900-5

[George Phillips]

                   I have conference rooms that have an IP 7970 with a shared extension of a VG FXS line. Until we upgraded to 8.6 we were able to establish a call on either device, and access the call from the other device without using any feature keys. Now it does not allow access to the existing call from either device.

How do we make open call access or Non-privacy on a DN happen on 8.6?

Hi George,

I would look @ using this feature/setting that you probably need on the VG

If you upgraded from a pre CUCM 7.0 version this wasn't required.

cBarge for Shared Lines

#

Allows idle IP or analog phones that are connected to the same FXS  ports on a Cisco VG2nn Analog Gateway to automatically join already  active calls on the same shared lines by simply going offhook.

cBarge and Privacy for Shared Lines

#

The cBarge feature allows any idle IP or analog phone on a shared line  or connected to the same port to automatically join an already active  call on the same shared line by simply going offhook. Through the Cisco  Unified CM, the three parties are allowed to hold a conference call.

---

#

Note Only  one analog phone is allowed to cBarge into an active call. When one  phone has already been allowed to cBarge into an existing conversation,  no other shared line analog phone can cBarge into it.

---

#

In  analog switching systems, a single analog port can be connected to  multiple analog phones such that when a phone is in an active  conversation, any other phone that is connected to the same port can go  offhook to join in the conversation.

#

In  digital IP switching (or PBX) systems, a similar capability is  supported and it is called a shared line. All the phones using the same  directory number are called shared line phones. When  there is an existing conversation on a shared line, going offhook  enables another shared line phone to cBarge into the conversation.

---

#

Note When  cBarge is configured, privacy might be an issue because any idle phone  on the shared line that goes offhook can join an existing conversation  regardless of the idle phone user's desire to join the call or not.

---

#

Privacy is a feature that blocks other phones on a shared line to cBarge into a conversation.

##

Configuring the port on a shared line on the Cisco Unified CM to  Privacy prevents other phones on the shared line to barge into active  calls.

We are using a VG248 and I am unable to locate "supplementary-service configuration" for ports on a 248.

Hi George,

No worries...that info won't apply to the VG248. If you don't mind I'd

like to test this out tomorrow in the lab and I'll get back to you here

Cheers!

Hi George,

I spent some time labbing this up today and discovered the

exact issues you described

I tried many things with privacy etc. and could not get things to work the

way you desire. Sorry man! The best I could do was to cbarge from the IP

phone into an active call on the VG248 analog phone/port.

After some further research I think this may actually be related to the VG248

release/version;

cBarge (Cisco CallManager 4.0)—Users with a Cisco IP Phone  sharing a line with a VG248 port can press the Conference Barge  (cBarge) softkey to automatically join a call in progress to the VG248.

---

Note You cannot invoke cBarge on the VG248-connected phone to join a call to a Cisco IP Phone.
