That could not be C because the call connects only audio is not flowing. That's a symptom of routing issues between the phone device and the gateway. Correct answer is B.

Selected Answer: C

Tail End Hop Off (TEHO) call routing extends the concept of toll-bypass. Instead of only routing intersite calls over an IP WAN link, TEHO also uses the IP WAN link for PSTN calls. You need to define dial peers to route calls using WAN link and also dial peers for using the PSTN link, in case the WAN link is not available. Hence it's the logical place to look for diagnosing TEHO issues. https://www.ccexpert.us/voice-over-ip/tailend-hopoff-teho.html
