IP Network Wide Virtual Office 1

[guycable2]

Hi
I have configured our Three CS1000 systems to use Virtual Office.

All three can use virtual office on their own sites but I have issues trying to log in as a user at another site.

Site A is a CS1000M MG Release 5.5
Site B is a CS1000M MG Release 5.5
Site C is a Cs1000E Release 5.0

I have verified that all of the phones in question have an SCPW and CLS vola voua.

I have verified on the NRS that NCS is checked for all three endpoints.

I have verified in Element Manager at all three sites that the node configuration under H323 GW Settings has the Primary NRS address is entered in the 'Primary Network Connect Server IP Address ' field, and the Alternate NRS IP address is configured in the 'Alternate Network Connect Server IP address' field.

These sites are connected by Point to Point T1s with a 4 digit CDP dial plan. There is no access code needed to dial the other sites. SIP trunks are the backup and each endpoint has been tested and works for routing calls.

I have also rebooted all of the sig servers and MC32 cards involved just in case.

Additionally one of my 1140 phones with C6R firmware keeps loosing the option for Virtual Office Login. A reboot of the phone seems to bring that back temporarily.

How do you dial users between the sites?

For example: Given several of my sites: MD1, MD2, NY, LA, Chicago

MD1 and MD2 are in the same CDP domain in NRS (MD1 & MD2 have 4 digit dialing between locations), all of the other sites use UDP (AC2+LOC+DN) to dial between sites.

If my phone is at MD1, and I am at MD2, then I go to a phone at MD2, go to Virtual Office Login, and enter my 4-digit DN as the user-ID, and my SCPW as my password.

If my phone is in NY, and I am in Chicago, then my user-ID for Virtual Office Login is: 8-04-5678 (AC2 + LOC of NY + My DN), and my password is my SCPW.

The user-ID must be in the dialable format that the NRS recognizes to route the call from location A to location B. You may need to make your SIP route the first entry in your RLI's for this to work properly.

Thanks for the suggestion. I will setup a separate RLI with SIP primary and point one of our ranges at it to test.

We are setup similar to your MD1 to MD2 sites. 4 digit between site a, b and c.

We aren't quite ready to go fully SIP between the sites yet. Hopefully soon.

I changed the RLI to one of our sites to use SIP 1st and it did not seem to change anything.

The error I get is Invalid ID(1). I do see contacting remote server first before the error.

One question I do have is do the Sig servers involved need to be enabled for SIP and H323 to use Network Virtual office? Mine are SIP only right now.

I have 10 sites in my network spread across the US and one in London - some are H.323 only, some are SIP only, and 2 have both SIP and H.323, with a mixture of 4.5, 5.0, and 5.5 systems. I routinely visit each site, and can log into my phone from every office.

Make sure you have the H.323 ID filled in under your signaling servers in the Node configuration for each site. For my SIP only sites, I just enter the SIP Gateway Endpoint Name in the H323 ID field, and that seems to work.

 

[guycable2]

Again thanks for the suggestion but still no joy.

I updated all three sites H.323 ID to be the SIP endpoint name. Still getting Invalid ID(1).

Anything else that you can think of?

I've gone over the settings in element manager and the NRS a couple times. Nothing jumps out at me. Calls do route fine over the SIP trunks so that is not the issue. I'll keep searching.

The Invalid ID (1) error is output when the user ID is not in the Gatekeeper database.

You need to make sure that your NRS database is accurate. Are you using CDP or UDP to dial between sites?

Again, if CDP, make sure both sites are in the same CDP domain, and that there are routing entries for each endpoint.

For Example, if site 1 hosts DNs 3100-3199, and site 2 hosts DNs 4400-4699, then you should have a minimum routing entry in site 1's endpoint for Private Level 0 CDP number 31 with a cost of 1, and in site 2 you would have Private Level 0 CDP entries 44, 45, 46 with a cost of 1.

If you use UDP, then you should have entries for each site's LOC code as Private Level 1 numbers in the NRS.

The Bottom line, is for this error, the number you are trying to use for the User ID does not exist in the NRS.

I can dial the extension and it goes across the SIP trunks so it is definitely in the NRS.

All sites are CDP. I have verified all the NRS CDP entries. There is only one CDP domain.

I'll keep digging.

 

[guycable2]

Got it working. Between two sites anyways. I have to schedule a reboot for the third.

I found the H.323 alias name under System Wide Settings on both the primary and secondary NRS servers was missing. I added the SIP endpoint name to that field on both servers and rebooted and it works.

I should add that I changed my RLIs back to use the tie trunks first just to see what would happen and it still works.

Thanks for you help with some of the direction as there were a couple things I needed to change. I also never thought about logging into the NRS by telnet and watching for errors. That helped me figure out why one site worked but not the other.

Glad to hear that it is working.
