SIP trunk registration failed

Your SIP trunk is not registered with the carrier, no outbound calls can be placed.

Symptoms

  • •All outbound dialing returns 503 or fails silently
  • •`sip show registry` shows Auth. Sent or Request Sent with no Registered state
  • •Inbound calls to your DIDs go nowhere

Common causes

  • •Wrong credentials on the trunk configuration
  • •Carrier changed registration endpoint or port
  • •Firewall blocking outbound UDP 5060 to carrier
  • •NTP drift, authentication hashes can fail if clock is off

How to fix it

  1. 1
    Verify credentials with your carrier portal
  2. 2
    Try `asterisk -rx 'sip reload'` to retry registration
  3. 3
    Check firewall: UDP 5060 outbound must be open
  4. 4
    Verify system time: `timedatectl`
  5. 5
    Review `asterisk -rx 'sip show registry'` for current state
