===== Troubleshooting =====
If your phone is not registering, or you are not able to make calls, check the User account, password and SIP server settings.

  * Ensure **[[troubleshooting:sip_alg:start|SIP ALG]]** is disabled on your router. See [[troubleshooting:sip_alg:start|this page]] for further information.
  * If those are correct, also check your [[..:..:nat_and_firewall_settings|firewall settings]].
  * Is your time correct? Check **Advanced -> Network -> NTP Time Server** (under Time) and if it is empty enter **0.uk.pool.ntp.org** or use your company's time server. Don't forget to set the correct timezone.
  * If calls are dropping after a certain amount of time (for example, every 15 minutes) then try disabling the **SIP Session Timer (s)** - this can be found under **Advanced -> SIP/RTP**.
  * If you are unable to receive calls intermittently then increase the **Keepalive interval (seconds)** frequency (lower number). For example, set this to 30.\\ This setting can be found under **Identity 1 -> NAT** (or use the relevant identity for your set up).
  * If you have tried the above and are still having trouble then try a different broadband router. We strongly recommend you use a business-grade router. [[http://www.surevoip.co.uk/contact-surevoip|Contact us]] if you would like a quote for a suitable business-grade router.

If you are still not able to connect, contact [[http://www.surevoip.co.uk/contact-surevoip|SureVoIP Technical Support]].
