Hi, We’d like to set up a SIP trunk between Vapi and our own PBX, but our company’s security policy requires us to pre-approve specific port ranges. Could you let us know which port range(s) Vapi’s SBC/PBX uses for SIP signaling and RTP media, so we can add them to our firewall allow-list? Thank you!

I can help you with any difficulty, let's have a chat now and proceed to your project

To set up a SIP trunk with vapi, allow UDP port 5060 for SIP signaling and UDP ports 10000–60000 for RTP media to/from IPs 44.229.228.186, 44.238.177.138, and 172.31.9.106..
