SIP Trunk Nepal — +977 Termination & DID Numbers
Nepal runs on UTC+5:45, one of the few time zones offset by 45 minutes, which trips up scheduling tools that assume whole or half hours. Most international traffic is diaspora calling from the Gulf, Malaysia and South Korea to 98x mobiles.
Overview
Routing calls to Nepal
Traffic to Nepal leaves our SBCs on more than one upstream carrier per prefix. If a leg toward Kathmandu or Pokhara starts returning 503s or long post-dial delay, the next attempt goes to another carrier automatically. Calls to Lalitpur, Biratnagar and Bharatpur follow the same failover logic.
Inside the country, numbers are dialled with a 0 trunk prefix. Strip it before you send the call, and send 977 followed by the national number. On the rate sheet, Nepal is split into geographic and mobile prefixes, following the plan set by the national telecom regulator, so your LCR can tell a cheap fixed-line call from a pricier mobile one.
Local numbers in Nepal are tightly controlled, so availability changes over time. Termination is available now. For DIDs, email sales with your use case and we will tell you what can be supplied compliantly.
