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
