Logging Missed Calls Shared line

With the missed call logging for shared lines feature, the administrator can configure Cisco Unified Communications Manager Administration, or the phone user can configure Cisco Unified CM User Options, so Cisco Unified Communications Manager logs missed calls in the call history to a specified shared line appearance on a phone. This will only work if [...]

I was looking into this customer issue where they upgraded from Call manager 4.x to 7.x and almost all users on 7912 phone lost their speed dials.

Posted: August 23, 2010 in Call Manager - CUCM, IP Phones & ATAs, MiscellaneousTags: Block corporate directory, Corporate directory restriction, CUCM 7.x, Personal directory
How you can restrict access to corporate directory? If you remember, corporate directory is accessible globally from a cluster and restricting its access needs some configuration changes. In pre-CUCM 7.x you cannot accommodate it at individual level but in CUCM7.x you have flexibility. You can run a sql command to access corporate directory information from [...]

Fax machines connected to ATA were not working. The first thing I checked on the gateway…is fax-relay was being used or fax protocol cisco was configured? Fax-relay is NOT supported by ATA. This is what I found at the Voice gateway: voice service voip allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to [...]

I was looking into this issue for a customer where a Conference phone, Cisco 7936, was not registering to Call manager. When I looked the MAC address of it in Call manager, it was in the status of ‘unregistered’ and there was an IP address assigned to it as well. This suggests that it somehow [...]
Scenario#10 – Phones showing Incorrect time

Posted: July 18, 2010 in IP Phones & ATAs, Real World ScenariosTags: 7975 IP phone incorrect time TFTP service
First step was to check if the Call manager is all synched and showing current time. Call manager was sysnched with an external NTP source (a gateway) and was looking good. Customer told me there were some Phone load issues. I found that the 7975 display debug shows it’s looking for a 4S load but [...]
