What are the security Settings for sipgate IP & Port Ranges?

Security settings for sipgate IP and port ranges including IPv4/IPv6 addresses for signalling and RTP across all sipgate services.

Currently sipgate services use the following address ranges:

sipgate.de

IPv4:

Type	IP	Port	Protocol
Signaling	217.10.79.9	5060	UDP
RTP	212.9.44.0/24 und 217.10.77.0/24	15000 - 30000	UDP

IPv6:

Type	IP	Port	Protocol
Signaling	[2001:ab7::1], [2001:ab7::2], [2001:ab7::3], [2001:ab7::4]	5060	UDP
RTP	[2001:ab7:2000:3::0/64]	15000 - 30000	UDP

sip.sipgate.de

sipconnect.sipgate.de

Note: IP addresses and port ranges may change due to expansions of our platform.

The IP address ranges used by sipgate are:

IPv4

• 217.10.64.0/20

• 217.116.112.0/20

• 212.9.32.0/19

IPv6

The above ranges are rarely changed. However, due to the demands of a modern agile work environment, at times we may need to add or remove IP address ranges.

If you experience one-way audio this may be due to changes to the IP ranges used by sipgate. The IP addresses you need to update in your firewall settings should be available in your connection logs.

For security reasons we further recommend:

• securing any SSH access options to your telephone system.

• changing the default passwords for web access to your telephone system configuration interface.

• blocking calls to premium/special numbers and expensive international destinations that you would not normally call.

Please always stay informed about the security recommendations of your VoIP system's manufacturer and keep any operational systems up to date.
