===== Troubleshooting =====
If registration is failing, check over the settings entered above.

Ensure **[[troubleshooting:sip_alg:start|SIP ALG]]** is disabled on your router. See [[troubleshooting:sip_alg:start|this page]] for further information.

If the Status page shows timeout, check over your [[..:..:nat_and_firewall_settings|firewall settings]].

Try using //TCP// instead of //UDP// for **SIP Transport**. This may help in situations where SIP ALG on a router is causing issues and there is no way to disable it.

If calls are cutting out, or the phone loses registration, enable or increase the frequency of SIP keep-alive settings. Set **Line 1 -> Registration Period** (under Basic SIP Network Settings) to a lower figure.

If you are still having trouble registering, contact [[http://www.surevoip.co.uk/contact-surevoip|SureVoIP Technical Support]].
