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

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

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

If you are having issues dialling out, go to **Regional** tab and at the **Vertical Service Activation Codes** section remove all the feature codes.

ie Call Return Code, Blind Transfer Code and so on should be blank.


If you find dialling international numbers causes beeping before you finish dialling, then under **Regional** tab and under **Control Timer Values (sec)** section increase **Interdigit Long Timer** and **Interdigit Short Timer**.

If you are experiencing issues with voice (hearing the caller or the caller hearing you and so on), then ensure you have followed **Step 5** above.

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