Yealink T18P

This guide explains how to obtain the IP address on the Yealink T18P as it has no display to easily display it.

Configuration of the SIP accounts is otherwise the same as the Yealink T2 range IP phones.

Obtaining IP Address

To obtain the IP address, simply dial **90# (asterisk-asterisk-nine-zero-hash). The IP address will be played back to you.

If you do no have an IP address automatically obtained, but you have a DHCP server running on your network, dial **88# then 1# to enable DHCP.

To disable DHCP, dial **88# then 0#

In the case where you do not have a DHCP server, or prefer to manually set an IP address, dial **80#.

Enter the IP address for the device, using * (asterisk) in place of . (period), followed by #.
For example, to set 192.168.3.4 you will need to type in 192*168*3*4#

Subnet Mask: **81# - followed by hash. For example: 255*255*255*0#.

Gateway **82# - followed by hash. For example: 192*168*3*1#.

DNS1 **83# - followed by hash. For example: 192*168*5*93#.

You can check these settings by dialling:

  • **90# for IP address
  • **91# for Subnet Mask
  • **92# for Gateway
  • **93# for DNS 1
  • **94# for DNS 2
