Hello, on a CCX 12.0.1 (HA Cluster) our customer is using webchat and would like to show real names on webchat instead of the usernames. I configured these names in the "agent alias" field but from time to time (after 1 or more days) the agent alias field is blank again and the system is using the username again. Is there someone with the same problem? Why is the system deleting the "agent alias" field? Thank you ... View more

Hello, we have a UCM Cluster in Europe (Germany) and we would like to add some Subscribers in USA but we have 125 ms RTT over MPLS WAN. In the Design Guide (SRND) for UCM 8.x there is a given number of 80ms RTT but I would like to ask if this is the absolut maximum or if it would be possible to have WAN Cluster with RTT about 125ms? SRND used: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/8x/uc8x.html Thanks for hints and answers. Andreas ... View more

Hello, we have two WISM Controllers running 6.0.196.4, a lot of 1252 APs and 100 7921 Phones with firmware 1.3.4(SR1). About 20-30% of the phones have the problem that from time to time (sometimes 3 times a day, sometimes after a period of 3-4 days and then 3-4 times a day) they are loosing theire network connectivity and showing "IP Configuring" on the display (device is not pingable in this moment). The only way to resolve the problem for the customer ist to power of the device. Some user could power of the phone via the power off button an some users have to plug the battery pack. This happen even when the phone ist on the desktop charger or when it is on the desktop. We tried to set fixed IP address but nothing changed so we think we do not have a DHCP Problem. In the same subnet we have more than 500 IP Phones (7962 and 797x) running without any problems. We think we do not have a roaming problem because this happens when the phone is not moving as well. Is there someone with with the same problem or a hint about that? Thanks ... View more
