If you are having problems registering your phone or PBX with our service then this may be due to a SIP ALG (Application Layer Gateway) on your router or firewall interfering with the SIP traffic or blocking it in some way. It may also be a firewall issue. We recommend in this case to try and use 'TLS' as your SIP transport (rather than the usual default of UDP). This will switch the traffic to an encrypted port which will effectively hide the SIP traffic from your network equipment.
If you do not have TLS transport as an option on your device then another work around is to switch the port number you use to register to us to be 50600 (instead of 5060) - this again can avoid ALG related problems since the port is unknown to the router as a SIP port. Usually the port is set on the end of the Outbound Proxy/Proxy address (e.g. phone.herotel.uk:50600) but can sometimes be in a separate 'port' field. Do not confuse your own SIP port with the one you are connecting to on our side. If in doubt contact email@example.com for assistance.
