UDP 5160
Synopsis
- UDP port 5160 is commonly used for SIP on Asterisk/FreePBX systems, specifically for the legacy chan_sip driver.
- In FreePBX 12+ and derivatives, PJSIP typically listens on 5060 while chan_sip was moved to UDP/TCP 5160 by default.
- Real-world deployments using this include Sangoma FreePBX Distro, PBXact, Issabel, VitalPBX, Incredible PBX, and RasPBX, where phones register to UDP 5160 when using chan_sip.
- SIP phones from vendors like Yealink, Grandstream, and Cisco SPA are frequently provisioned to point to UDP 5160 when connecting to these PBXs.
- Many standalone Asterisk setups also bind chan_sip to UDP 5160 so PJSIP can remain on 5060.
- Because UDP 5160 often carries SIP, it is a common target for VoIP scanning, brute-force registration attempts, and toll-fraud attacks.
