Refer to the exhibit. When extension 201-555-1000 dials 404-555-1200, how are the digits manipulated in R1 so that they are presented correctly at R2?

A.
The outbound VoIP dial peer is matched and all digits are sent.

B.
The digits 404-555 are stripped off before matching the outbound POTS dial peer.

C.
The digits 404-555 are stripped off by the connection trunk and R2 receives only 1200.

D.
R1 collects the 1200 and prepends the tie-line digits 404555. That number is matched to a VoIP dial peer and sent to the appropriate address.

Explanation:
When 201-555-1000 (Phone A) calls 404-555-1200 (Phone B) the dial-peer voice 1 voip at R1 is matched with the destination-pattern 404555. But notice that this is a voip dial-peer so digits are not stripped and all digits are sent to R2.
