CUBAC and Presence


I have a new CUBAC 8 with CUPS 8 and CUCM 8

I have configued the CUPS section on CUBAC and when I do the test connection it is successful

I have added the CUBAC server to the incoming/outgoing ACL on CUPS

However I do not have phone / line presence information on CUBAC

Have I missed anything?

Many Thanks

Re: CUBAC and Presence

Best way to do fault isolation is to test the phone presence with a CUPC client.

If you can see phone presence on CUPC client, the problem is on CUBAC/CUPS integration.

Otherwise, the problem is on CUPS/CUCM integration.  You might want to check capability assignments, line apperance assogication, etc.

Re: CUBAC and Presence


CUPC client appears ok and can see presence

There does not appear much to do on the CUBAC to CUPS integration.

What would I check?


Re: CUBAC and Presence

As far as I know, this part of feature is very buggy on previous version of CUBAC, such as shared-line, multi-line support.

You'd better check with TAC to make sure you're not hitting those bugs.

Re: CUBAC and Presence


Whilst I thought my CUCM - CUPS integration was fine I am now not sure - It is not fiully deployed yet

I have 2 test users on CUPC

they can each see their presence and we can see each others fine.

I am using extension mobililiy

However when I go to the presence viewer

I put my user id - it basically comes up with line presence status unknown.

Each UDP line has the user association

each user has standard cti enabled

each user has CUP/CUPS capabilities in licencing

What am I missing


Re: CUBAC and Presence

Availability and phone presence are two different features.

In your very first post, you said "I do not have phone / line presence information on CUBAC"

Were you able to see "phone / line presence" from CUPC clients?

Re: CUBAC and Presence


I only have two users working on CUPC at present

However if I log onto CUPC and also log onto phone I can see my presence status - on hook etc

Also can see the other user's presence status

However If I go to presence viewer and do a presence view based on my id against the other id I have no presence information for the other persons line.

does this make sense?

Re: CUBAC and Presence

Two things on the CUBAC side:

    1. In their infinite genious, Arc doesn't show the CUP status column by default within the client. You will need to go into client preferences and add it. It may be working but not showing.
    2. It appears that you need to specify the CUP Proxy Domain on the CUBAC configuration page, even if you are not doing TLS. It adds that value to the username to perform a SIP SUBSCRIBE.

Also, loading presence can take a bit after performing a search; give it a bit. On the phone or in a meeting are displayed as a red 'Busy' state instead of the typical yellow color from CUPC.

Re: CUBAC and Presence

Let's do this step by step.

Assuming you have two users - user A and B.

1) If you logged into CUPC as user A and add user B to the contact list, would you be able to see user B's status as "Available" (green)?

2) If user B picks up his phone, from user A's CUPC, would you be able to see user B's status change to "On-The-Phone" (yellow)?

Re: CUBAC and Presence

Hi Michael,

I have two users on CUPC and each user can see availaiblity and presence information of each other - These users are EM users

So yes user A picks up phone and user B sees on phone, vice versa

However in the presence viewer I do not see presence information.

So I think my SIP trunk is ok, but how come the presence viewer does not show this information?

This widget could not be displayed.
