What would work best?

[5ascent0]

Current Scenario:
Headquarters with 50 2420 phones and an IPO 406
8 Construction sites with 2 4640 phones each

Network is a Cisco PIX 506 at the headquarters and Cisco PIX 501's at 6 job sites. I have also deployed a Tsunami 100 (100mb full-duplex wireless bridge) that serves as a backhaul to a roof top that is then connected to 2 of the other job sites via Tsunami QuickBridge 20's.

The client is being kicked out of their headquarters in 30 45 days and their new building will not be ready for six months. I have to split the headquarters up between two buildings 4 miles apart. I can set up another Tsunami 100 unit between the two, however I am unsure as to how I would split up the phone system. Would one stay as the main location with all incoming phones lines, while the other location would connect to it via a WAN3? What would be the best scenario?

Thanks in advance, I am meeting with the client at noon tomorrow to discuss the logistics.

Unless you're going to put half those 2420 phones in storage and buy IP hardphones, you're going to need a 403 w/VCM card and a Digital 16 port to do this. Your customer will think the sun and moon revolves around you if you offer to rent them a unit instead of forcing them to buy it. I wouldn't suggest that for phone sets, but the 403 should come out in perfectly good shape at the end of the 6 month stint. Just ensure it goes in a locked room in a proper data rack.

You wouldn't need a WAN3. Either use the built in WAN ports on the 406/403, or simply ethernet ports on the front depending on what your network gear allows.

Personally I would divvy up the trunks between the two locations.

PS Hope this got posted in time to help, "tomorrow at noon" can mean a whole range of things in this forum

Client had 10 2420 phones on the shelf so I will use them for most of the phones and 2 4620 phones for the rest. Also, they are bridged using a Tsunami 45 so the are all on the same subnet. How do I connect the 403 to the 406 using the ethernet ports, and how can I keep the users with the same extensions after they go over to the 403? We are trying to make the change as transparent as possible. I did receive the 403 this morning and will be implementing tonight.

The docs lay it out very clearly how to connect two IP Offices via a LAN connection (with what you're doing for all intents and purposes just forget that it's going over a WAN). Each unit gets its own ip address, then you create voip trunks from one to the other (telling it the ip address of the far-end IPO) and vice-versa, ticking the 'Voice Networking' option at both sites which activates the SCN. Be sure all your extensions are unique - in other words, renumber any unused extensions at site A out of your usual range, ditto at site B. Thus you can have 3201-3205 at site A, 3206 at Site B, 3207 at Site A, 3208-3212 at Site B and so on with unused ports numbers as, say, 5001 and up at site A and 6001 and up at site B.

Once you have that going, all that is left is to setup the site where the VMPro will NOT be to use a centralized voicemail. Change the type from PC to LINE and give it the IP address of the Voicemail server. That's really all there is to that but there is also a good job aid on centralized VMPro if you need to refer to it.

Let us know if you have any trouble, I love this kind of stuff

Will a single channel VCM card work, or will I need more? Does the unit create a Voicechannel for every user, including the digital users at the 403 side, when they are on the phone?

If possible, could I call you if I have problems. I am a vendor in Vegas.

No such thing as a VCM1, dude. In a 403 you can have a 5, 10, or 20 VCM (max 18 voip calls).

You will need 1 VCM channel for every voice conversation that traverses your WAN. This includes users on the 403 checking VM (assuming you put the VMS on the 406). For this reason I hope you decided to divvy up the trunks between the two sites, otherwise every PSTN call in/out of the 403 would also take up a VCM resource.

Note that whichever site has the smaller VCM defines the bottleneck. Ie VCM5 for 403 and VCM10 for 406 = MAX of 5 callers between sites.

No trunk or phone service exists at the 403 side. We are running the Tsunami 45 ptp link. So, all calls will need a vcm channel.

 

[Morrack]

For 12 users?? How often will they on the phone on the 403 side? I would go with a VCM 10 at both ends personally...

 

[5ascent0]

I am going with a VCM 10 at both sides. It will be about an hour before I start the config. Had some other issues on the network. ...let you know how it is going.
