Comment: Added additional information on caveats for creating multiple transports


You can setup multiple transport sections and other sections (such as endpoints) could each use the same transport, or a unique one. However, you may only configure multiple transports as long as they do not there are a couple caveats for creating multiple transports:

  • They cannot share the same IP+port or IP+protocol combination. That is, each transport that binds to the same IP as another must use a different port or protocol.
  • PJSIP does not allow multiple TCP or TLS transports of the same IP version (IPv4 or IPv6).


Reloading Config: Configuration for transport type sections can't be reloaded during run-time without a full module unload and load. You'll effectively need to restart Asterisk completely for your transport changes to take effect.
