Using sipgate with a firewall

Here you will find IP addresses, ports and configuration notes for smooth operation in your company network.

Signaling & audio transmission (SIP & RTP)

These endpoints are used for SIP signaling and RTP voice transmission. Which rows are relevant depends on which sipgate product you use.

sipgate apps

Additional services are integrated to use all features of the sipgate apps. In addition to the permissions from "Signaling & audio transmission (SIP & RTP)", further firewall permissions are therefore required, for example for real-time events, contacts, and app updates.

sipgate app

Depending on the account, the sipgate app runs on one of two platforms: the modern neo platform (NeoPBX) or the older classic platform. Both use different backend infrastructures, which is why the required permissions differ. You can see which platform your account uses after logging in, at the top right in the account.

Basic requirements for trouble-free telephony

Your internet connection should meet the following basic requirements:

Criterion
Requirement

Bandwidth

approx. 100 kbit/s per simultaneous call (upload and download)

Latency (round-trip)

under 250 ms

General recommendations

  • Firewall rules usually only need to be configured for outbound traffic.

  • When using SIP via UDP, we send keepalive packets every few seconds after registration. If these packets do not arrive and the end device itself does not send keepalive packets, the end device may be unreachable from the outside. Switching to TCP can help here.

  • Static port forwarding to specific end devices is usually not necessary and poses a security risk.
