Configuring DNS on ShoreTel Voice Switches

Content

To ensure that a switch on which you have configured SIP trunks for Connect HYBRID Sites can connect with the ShoreTel Connect CLOUD system, you must configure DNS on the switch as described in this article. Because the process differs slightly for various switch models, follow the procedure for your switch model.

Verify that the IP address of the switch is static; otherwise, inserted entries will not be saved.

The following procedure applies to these ShoreTel switch models: 30, 30BRI, 50, 50SB, 50BRISB, 90, 90BRI, T1k, E1k, 220T1, 220T1A, 220E1.

  1. Telnet to the switch.

  2. If the switch displays "->" instead of the "ShoreTel>" prompt, enter cliStart.

  3. At the "ShoreTel>" prompt, type 3 and press Enter.

  4. At the "ShoreTel Config>" prompt, type P and press Enter.

  5. For the new primary DNS, type the IP address of a server that can resolve DNS entries for external FQDNs, and press Enter. (If you do not have a server that can do this, you can use 8.8.8.8, which is a public DNS for Google. However, ShoreTel is not responsible for any issues that arise because of the use of this public DNS.)

  6. At the "ShoreTel Config>" prompt, type S and press Enter.

  7. For the new secondary DNS, type the IP address of a server that can resolve DNS entries for external FQDNs, and press Enter. (If you do not have a server that can do this, you can use 4.4.2.2, which is a public DNS for Google. However, ShoreTel is not responsible for any issues that arise because of the use of this public DNS.)

  8. To exit, at the "ShoreTel Config>" prompt, type 0 and press Enter.

  9. To reboot the switch, at the "ShoreTel>" prompt, type 4 and press Enter.

  10. To proceed, type yes and press Enter.

  11. To save the changes, type y and press Enter.


The following procedure applies to ShoreTel virtual switches, ShoreTel ST- generation switches, and ShoreTel 50V, 90V, and 90BRIV voice switch models:

  1. SSH to the switch.

  2. Log in as Admin.

  3. At the "->" prompt, type stcli and press Enter.

  4. At the "ShoreTel>" prompt, type 3 and press Enter.

  5. At the "ShoreTel Config>" prompt, type P and press Enter.

  6. For the new primary DNS, type the IP address of a server that can resolve DNS entries for external FQDNs, and press Enter. (If you do not have a server that can do this, you can use 8.8.8.8, which is a public DNS for Google. However, ShoreTel is not responsible for any issues that arise because of the use of this public DNS.)

  7. At the "ShoreTel Config>" prompt, type S and press Enter.

  8. For the new secondary DNS, type the IP address of a server that can resolve DNS entries for external FQDNs, and press Enter. (If you do not have a server that can do this, you can use 4.4.2.2, which is a public DNS for Google. However, ShoreTel is not responsible for any issues that arise because of the use of this public DNS.)

  9. To exit, at the "ShoreTel Config>" prompt, type 0 and press Enter.

  10. To reboot the switch, at the "ShoreTel>" prompt, type 4 and press Enter.

  11. To proceed, type yes and press Enter.

  12. To save the changes, type y and press Enter.
