Important: IP addresses are subject to change. Always verify the latest list with the Vobiz team before making firewall changes. Contact support@vobiz.ai to subscribe to IP change notifications.

SIP Signaling

Allow inbound and outbound SIP traffic from these IPs. Used for call setup, tear-down, and control messages between your SIP infrastructure and Vobiz. India

IP Address	Protocol	Port	Direction
`13.203.7.132`	UDP / TCP	5060, 5061	Inbound + Outbound
`65.2.100.211`	UDP / TCP	5060, 5061	Inbound + Outbound
`13.126.98.234`	UDP / TCP	5060, 5061	Inbound + Outbound
`13.235.11.131`	UDP / TCP	5060, 5061	Inbound + Outbound
`13.233.44.61`	UDP / TCP	5060, 5061	Inbound + Outbound
`3.111.255.163`	UDP / TCP	5060, 5061	Inbound + Outbound
`3.111.128.110`	UDP / TCP	5060, 5061	Inbound + Outbound
`43.204.64.203`	UDP / TCP	5060, 5061	Inbound + Outbound
`15.207.232.91`	UDP / TCP	5060, 5061, 5063	Inbound + Outbound
`35.154.133.28`	UDP / TCP	5060, 5061, 5063	Inbound + Outbound

Firewall rule: Allow TCP/UDP on ports 5060 and 5061 for all SIP signaling IPs in both directions.

RTP Media

Allow UDP traffic from these IPs for the audio media stream. RTP carries the actual voice packets during a live call. India

IP Address	Protocol	Port Range	Direction
`3.110.99.6`	UDP	5000–65535	Inbound + Outbound
`65.1.145.87`	UDP	5000–65535	Inbound + Outbound
`13.234.214.51`	UDP	5000–65535	Inbound + Outbound
`13.200.197.87`	UDP	5000–65535	Inbound + Outbound
`13.202.13.57`	UDP	5000–65535	Inbound + Outbound
`18.96.230.96/28`	UDP	5000–65535	Inbound + Outbound
`18.96.230.112/28`	UDP	5000–65535	Inbound + Outbound
`18.96.230.208/29`	UDP	5000–65535	Inbound + Outbound
`18.96.232.168/29`	UDP	5000–65535	Inbound + Outbound

Firewall rule: Allow UDP port range 5000–65535 for all nine entries in both directions.

Callbacks

Vobiz sends webhook callbacks from these IP addresses to your server. Allow inbound HTTPS traffic from these IPs so your application receives call status, hangup, and recording events. India

IP Address	Protocol	Port	Direction
`15.206.6.156`	HTTPS	443 (80 for HTTP)	Inbound to your server
`35.154.59.246`	HTTPS	443 (80 for HTTP)	Inbound to your server
`15.207.8.226`	HTTPS	443 (80 for HTTP)	Inbound to your server

Firewall rule: Allow inbound TCP port 443 (HTTPS) from all three IPs to your callback server. Port 80 only if you use plain HTTP callbacks.

Protocol Whitelisting

In addition to IP addresses, ensure your firewall and ISP do not block the following protocols.

Protocol	Port	Use
SIP	5060 / 5061	Call signaling (setup & teardown)
RTP	5000–65535 UDP	Voice media streaming
HTTPS	443 TCP	Callback / webhook delivery
WSS	443 TCP	WebSocket streaming (XML Stream)
