Answer:

1) Look for the incoming called-number command in the dial peer that matches the called number or DNIS string in the inbound call leg.
2) Look for the answer-address command in a dial peer that matches the calling number or ANI string of the inbound call leg.
3) Look for the destination-pattern command in a dial peer that matches the calling number or ANI string of the incoming call leg.
4) Look for the POTS dial peer port configuration that matches the voice port associated with the incoming call (POTS dial peers only).
5) If no matches are found, the system uses the default dial peer.

Question 7

Answer:

Step 1:  Sampling
Step 2: Quantization
Step 3: Encoding
Step 4: Compression (optional)

Explanation

Below is a summary for each step:

1) Sampling: The sampling rate must be at least twice the highest frequency, to accurately represent the original signal.
2) Quantization: consists of a scale made up of 8 major divisions or chords. Each chord is subdivided into 16 equally spaced steps. The chords are not equally spaced but are actually finest near the origin.
3) Encoding: encode the value into an 8-bit digital form.
4) Compression: compress the samples to reduce bandwidth. Although not required but it is widely used.
