Hi all,

Does anyone know how to configure this?

Hi Hoanghiep,

You have two options, one being more straight forward than the other to implement, this depends on your requirements.

Firstly you can configured both phones with the same DN, thus making them a shared line appearance. For example if you configured DN 1234 on both phones then when you dial 1234 both Phones will ring simultaneously.

The second option is applicable if you require both phones to have unique DNs that ring at the same time. If this is the case then you can configure these Phones as members of a broadcast line-group.

A line group allows you to designate the order in which directory numbers are chosen. Cisco Unified CallManager distributes a call to idle or available members of a line group based on a call distribution algorithm and on the Ring No Answer Reversion (RNAR) Timeout setting.

There are three steps for configuring this method:-

1. Configure the Line-Group and associate members/extensions.

2. Configure the Hunt-List and associate the Line-group in step 1 with this list.

3. Configure the Hunt-Pilot which is the specific number to call in order to route the call the line-group members. Here you associate the hunt-list in step 2.

Look at the folloing links for configuring the above:-

3.Hunt-Pilot

Hope this helps.

Thanks for your reply. But the 2 solutions you listed are not applicable for my case.

1. The 2 phones are in 2 separate clusters so we cannot use SHARED LINE. So the 1st option is not suitable for this case.

2. A line group member must be a Directory Number in which FORWARD feature no working. So the 2nd option of yours is not suitable too.

Any other ideas?

Thanks,

indeed Line Group ignores CFwdALL of DNs.

Could you please clarify why you want two Phones in two Cluster to rings simultaneously? maybe we can find another solution for you.

Apologies Hoanghiep, I misread your original requirements '2 CCM Clusters' kind of gives it away..
