Synopsis

  • FreeSWITCH uses TCP port 5080 for its “external” SIP profile by default (SIP signaling on 5080/TCP and 5080/UDP; TLS on 5081), separating external trunks/peers from the internal profile on 5060/5061.
  • FusionPBX, which runs on FreeSWITCH, inherits this default and commonly exposes external SIP services on TCP 5080 in real deployments.
  • 2600Hz Kazoo (a carrier-grade VoIP platform built on FreeSWITCH) likewise uses the FreeSWITCH external SIP profile, so deployments often listen on TCP 5080 for external SIP trunks/endpoints.
  • Security note: because TCP/UDP 5080 is a known SIP port on FreeSWITCH-based PBXs, it is frequently scanned and targeted for SIP toll-fraud (e.g., brute-force REGISTER/INVITE attempts), similar to the more common 5060.
