I have several call center agents using softphones running on build 260. The BCM450 has all the current patches installed. All of the phones on the BCM450 are IP phones, just the call center gang uses softphones. The PCs with the softphones are on a different subnet than the BCM and the other IP phones.
Example. Agent PC/softphone 192.168.10.50
Wired IP phone 192.168.20.50
The intermittent problems they are experiencing are losing connection to the BCM,dropping calls, agents are unable to log in, unable to hear callers or people they call. The last problem is more common when calling internal extensions.
We tested connectivity of the PC to the BCM during one of the "server unreachable" episodes and the PC could ping the BCM with a <1ms round trip delay. The layer 3 device on the network is a Nortel 2526 with static routes between the two networks. The data switches are all Nortel 470 POE switches and the PVID is set to 10 which is the VLAN number for the .10 network. The BCM450 is on a port set to PVID 20 which is the VLAN ID for the .20 network.
I have been researching the no speech path issue for the internal calls and I believe it has to do with the PVID setting since the wired phones almost exclusively have a PC connected to the data port. The wired phones network config has 802.1Q enabled for both voice and data with the associated VLAN ID entered. I am testing setting the PVID of the port where the wired phone is connected to 20, but have not gotten any firm proof as of yet this resolved this specific issue.
I have not encountered these kind of issues ever...in the last 5 years anyway with the I2050 phones. Usually if the phone registers it's all good with those. Has anyone had issues with the I2050 on the BCM450?
