Generic Voip Settings

If your device is not listed in our user guides then you can usually register any generic SIP v2 compliant device with just a few basic settings. The workings associated with the settings can differ from device to device but generally you should only need the following settings to get registered to iTelco:

  • Login/Username/ID: your-itelco-number

  • Authorisation Username/ID: your-itelco-number

  • Password: your-itelco-password

  • Domain/Realm:

  • Proxy:

  • Outbound Proxy:

  • Use Outbound Proxy: yes

  • Register Expires: 600

  • DMTF Mode: RFC2833 (or AVT/out of band)

The DTMF mode should be 'inband' in the case where fax machines or alarm systems are being used. There are other settings that can be configured but may differ from device to device on how these are implemented, but in general terms we usually advise customers set the following:

  • Preferred Codec: G.711a (or alaw)

  • Secondary Codec: G.711u (or ulaw)

  • Other default supported codecs: G.722, G.729a, GSM

  • T.38 support: Enabled (for fax machines or alarms)

  • Echo cancellation: Enabled (except for fax machines or alarms)

  • Silence Suppression or VAD: Disabled

If you are unsure about these settings or have any other questions then please contact iTelco support.
