CCIE Voice
From MSN to DDI
I really hate when customer plays unfair – doing big change in services without notice. It was this time with approximatelly 30 remote offices each with 2 bri interfaces.
In the half of them we met an issue. Conections wasn’t established properly. After searches solution was to reconfigure bri interfaces as below
isdn tei-negotiation first-call
isdn tei-negotiation power
isdn tei-negotiation powerup
isdn static-tei 0
Important: clear interface
CCIE Voice Lab
I saw a scheme how the lab looks like for CCIE Voice Lab exam. At least it is easier to learn build something similar to test, learn and troubleshoot most common issues and implementation tasks.
All looks clear except new version contains Cisco Presence – new to me – never implemented, never supported – yet. Secondary I wonder how important is Exchange server during lab exam. I hope it is just a tool to check some functionalities.
