Symbol Netvision Wireless IP phones

Hi,

we are currently in the process of implementing an Cisco AAVID solution for a client.

We have at this point a single call manager supporting about 50 - 70 phones across 2 offices.

This setup is fully functional at the moment, and is not having any problems (it will be expanding shortly, etc).

The problem we are experiencing is the configuration of some Symbol Netvision Wireless IP phone handsets.

We have liased with Symbol extensivley on how these phones should be configured in relation to the call manager side of things, but have gotten nowhere.

We have been assured by Symbol that these phones WILL work with call manager and they verify that they have tested them with call manager themselves and not had any problems.

They did specifically upgrade the firmware for CallManager.

The problem we are having is that although we can assign the phones IP addresses and all the other relevant network details, we are unable to get CallManager to recognize the phones. The phones remain "Not Registered" and call manager is never able to resolve the IP of the phone from the MAC address that we specify.

We are able to ping the phones from the call manager as well as perform an ARP resolution of the IP address so I cant envisage this being a network problem.

Has anyone tried a similar setup and experienced these problems or actually gotten it working?

Any help is appreciated greatly.

Thanks

Re: Symbol Netvision Wireless IP phones

Need a little more info... but we have a similar sounding setup and it does work. 60-70 NVP's running on Symbol 3021 AP's. NVP firmware can be problematic; have had good luck with 3.60-20PR. Pls post or send more info about setup - CM ver, CM NVP setup/load, NVP fw, AP's, etc.

I have also had problems with the netvison phone for our callmanager system ,and have been informed that the standard phone wil not work with the callmanager and that you need to install the firmware that includes Cisco Skinny client and also the configuration software from Symbol that is specifically for configuring for Callmanager. Haven't managed to successfully implement this as I am still waiting on a serial cable/ replacement phone as mine locked up prior to this and hasn't come back yet!

good luck!

Take a look at SpectraLink NetLink IP Phones. They work with Call Manager version 3.08+. http://www.spectralink.com/products/NetLinkIP.html

Re: Symbol Netvision Wireless IP phones

need a little more info. Are you running the Netvision phones with the CM skinny client available from Symbol or the standard Netvision using H323? We have been able to get the standard Netvision to work with H323 and a Cisco AP350. Did you configure the h323 setup in CM for the phone? The skinny client makes the Netvision act like a 7940 phone and will use DHCP for configuration in CM.

Re: Symbol Netvision Wireless IP phones

we looked at and had several phones in from symbol in december. it did not work. after running some sniffer traces we found out the code running on the phone was appending the domain name on to the name of the call manager that was found in the sepdefault.cnf file. now this sounds good except that the file all ready had the fully qualifed domain name. so the phone was trying to do a dns lookup on cm1.company.net.company.net after finally getting in touch with the programers direct we convinced them that the phone was in fact doing that. they have claimed to have fixed the problem but we have not invited symbol back to test. I wouls sugest that you get the latest code and maybe talk to symbol tech support and confirm that you are getting code that fixes the above problem. we are running 3.1.2c on the call manager hope that helps

Robert,

We have found that the Spectralink Wireless IP phones to be excellent. They only require their server software to provide QoS over the 802.11b link until the QoS capabilities/standards for wireless has been ratified later this year. Give them a go, they really do work well.

Cheers.

Chris
