Refer to the exhibit. The Carmichael caller dials the site access code for Merrimack (6) followed by the four digit extension number of the destination phone (0124). If the call is going to go across the IP WAN, which action will have to be taken?

A.
Translate 60124 to 5125550124.

B.
Strip the site access code and send four digits.

C.
Strip the site access code and prepend 1512555.

D.
Do nothing because the site access code matches the last five digits of the target number.

E.
Strip the site access code, send four digits, then prepend the access code when it reaches the Merrimack gateway.

Explanation:
The site access code (6) is just used to inform the originating gateway which gateway it needs to send traffic to. Therefore, after learning the traffic should be sent to Merrimack gateway, it trips off the site access code. Notice that the receiving gateway will receive 0124?, which is enough information to ring the phone plugged into it.
