Multi line appearance

[bignose21]

We are replacing a CS1k solution that has a couple on Media Gateways, there is an emergency room on it and they have set appearances (Digital phones) in 2 different rooms with a port from each gateway in each room (4 appearances for every phone). So in effect if there is a gateway issue for example they can just unplug the phone from Gateway 1 and plug it into gateway 2 and carry on working with exactly the same setup. If there is a problem that requires a move of location to another area in the campus they have the same setup in another building. Each of the phones (3 users) has 8 line appearances on them, we have a server edition IP office as a replacement with 2 ip500V2 and want the same sort of solution (Sets will remain as Digital). An example of what the phones look like (numbers not exact):

phone 1 phone 2 Phone 3
1 1000 2000 3000
2 2000 1000 1000
3 3000 3000 2000
4 4000 4000 4000
5 4001 4001 4001
6 4002 4002 4002
7 4003 4003 4003
8 1100 1101 1102

In the CS1k all the keys are MCR so they all alert for all incoming calls. couple of questions:

Is the best way going to be Hunt groups set to consecutive ringing as these can be across the two gateways?
Or is it possible to share DN's across the gateways?
Is there a way to configure DN's that are not against other sets (So i realise that say if I config set 1000 I could then add it on the same gateway as an MADN or Bridged extension) like in the case of DN 4000?
Or would the best way in fact be to config the users just in one place (Like in the primary server, backed up in the secondary) and then use the user login to drag the details to the phone they are using on either gateway?

so just to clarify, you are going to run IP office Server addition and replace the existing Media Gateways with IP500's? is this what you are wanting to do?

And you are doing this for redundency in the event one of the IP500's fail, you will have them move to the second IP500? am I following this correctly?

I'd go with groups or extension logins to users that are built on the servers. You can't do bridged appearances or MADN across systems.

 

[bignose21]

Z-man that's correct

Biv343 that's kind of what I was thinking or hunt groups.

Only other thing is can you just config extra DN's on the higher keys or do you have to create a user for each DN so that you can then assign the appearance to other users?

CS1000 is a bit different than IP Office. With IP Office you can accomplish a solution several different ways, which can be great, but frustrating at times. Sometimes it is best to work from the finish and reverse engineer so to speak.

What exactly is the end desire of these phones? What do you want them to be able to do? Once you tell us that, we can advise a solution that will be the most efficient.

Also, how many digital phones are you going to have on each IP Office 500? just curious. You have only mentioned two, so I wasn't sure.

We have had to stick with a setup from previous ISDX we moved it into the CS1K some years back. The 3 users are in a control room that is very important to remain in service. They use digital sets and want to stick to that technology. So each of the 3 positions has two ports (one from each MG) to mitigate a failed gateway (they used to be off 2 separate ISDXs). Then in case there is a reason that they need to leave the room there is another room elsewhere in the campus with the same setup.

Each user has a repeat of the other two users DNs and several shared DNs (8 numbers on each phone used for different groups to contact them). Layout pretty much as detailed in previous post.

We need to maintain the digital sets and give them a port off each gateway in each room so 4 ports for every user.

These systems only have a low number of control room users and incident rooms, so plenty of capacity in the 2 IP500v2.

I was asking because you had IP sets on the CS1000 right? coming off of the Gateway's? Its been a long time since I dealt with CS1K, so I don't remember if the gateways had or took digital cards. In the IP Office world there is no difference in funcationality between digital and corresponding IP sets. Just in the internal delivery. But getting back to your original question, you really cannot put DN appearances on a phone like in the Nortel setup. You would want to direct all the calls to a groups obviously, and just make that group ring the appropriate phones as needed. In case of failure, the user switches to a new physical port and logs in as their original user, so the programming never changes, just basically the delivery route. Personally I don't see the need for th IP500's when you can just connect some IP sets and by pass a failure point. But like I said previously, you can accomplish the end result several different ways depending on your preference.

The CS1k phones were also digital (3904) recorded through TALC cards to Telstrat server, this group has shied away from IP as there has been issues in the past with the network in that area, and as you can imagine back in the day their PC's were down but they still had all the phones on the ISDX, so when we replaced it some years ago with CS1K they insisted on keeping the TDM service. Hence now we also need to stick with the digital's on the IPO, before you say work on the resilience of the network in the area we also tried to push that to no avail.

The only problem i see is how to supply the numbers as I guess I need to create an extension for each number to be able to assign it to a key on a user, unless like you say they will accept group numbers that arrive on their individual numbers. So as you can imagine currently they will have keys labeled with the Group Name of who's calling, say call for 4003 lands on everyone's key 7 labeled "pipe line".

So given the above example I would need to configure extensions 1000,2000,3000,4000,4001,4002,4003,1100,1101,1102 then add user 1 assigned to extension 1000

key 1 appr 1000
key 2 MADN 2000
key 3 MADN 3000
key 4 MADN 4000
key 5 MADN 4001
key 6 MADN 4002
key 7 MADN 4003
key 8 MADN 1100

And similar idea for the rest of the users?
