Twilio Elastic SIP Trunking DocumentationSIP Trunking

Description

Possible causes

possible-causes page anchor
  • Authorization failure - source IP Address not in ACL (Access Control List).
  • There is an ACL on your trunk and you are sending us INVITE requests from an IP address not on that ACL. Either fix local routing so that you are sending us SIP from an address already in your ACL or add this other address to your ACL.
