Errors that occur when using VoIP are often caused by the router. However, with very little effort these problems can usually be resolved quickly. If you use a router and/or a firewall, some settings can be adjusted so that you can use sipgate without any problems.

Common errors which can be caused by the use of a router and/or firewall are:

• Your device does not connect to sipgate (status "offline") or loses connection after some time.
• The phone rings on the other line, but you cannot hear anyone talking.
• Even though you have hung up, the phone continues to ring.
• You cannot be reached from external phones.
• You select a number, but cannot hear it ring.
• As soon as someone picks up the receiver, you can't hear anyone talking.
• The call is disconnected after 6-12 seconds.

These errors do not always show up all the time and sometimes only occur after a few hours or days. In most cases, a firmware update of the router should suffice with clearing up the problem. Please contact the router's manufacturer for additional assistance.

Port forwarding:
If you are still having problems with the connection afterwards, please activate forwarding for the following ports on your router/firewall:

Standard:

• Port: 5060 / UDP (SIP)
• Port: 5004 / UDP (RTP)
• Port: 10000 UDP (STUN) 

X-Lite:

    * Port 5060 / UDP
    * Port 8000 - 8019 / UDP
    * Port 10000 /UDP

 
Tips for Universal Plug and Play:
If your router supports UPnP (Universal plug-and-play), it might be helpful to turn this option on or off in the last step.
 
Note: Please take into account that the assigned ports do not necessarily apply to every device.  Please refer to more specific information from the configuration instructions of the respective manufacturer. If you have forwarded the ports as indicated and errors still occur, you should delete the STUN server from the configuration of your device.
