Dial peer selection
Sometimes there is a need to configure more complicated configuration for incoming or outgouing calls. It’s good to remember what is an order of dial-peer’s selection by matching epcific elements. So it selects as below:
1. incoming called-address
2. answer-address
3. destination-pattern
4. voice-port
In the case of some issues start debug remembering that it is enough for gateway to match one of those elements.
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
