Manually Register a Grandstream IP Phone with Cloud Voice

When a Grandstream desk phone is not provisioned automatically, you can register a Cloud Voice extension on it by hand. The workflow has two parts: first you collect the extension’s SIP details from Cloud Voice, then you type those details into the phone’s web interface. The steps below use a Grandstream GRP2602 (firmware 1.0.3.67) as the example, but any Grandstream phone that supports SIP (Session Initiation Protocol) follows the same pattern.

Step 1. Collect the registration details from Cloud Voice

Sign in to the Cloud Voice management portal and write down the following values. You will enter each of them on the phone in Step 2.

Extension credentials

Go to Extension and Trunk > Extension, click the edit icon next to the extension, then open User > Extension Information. Record these three fields:

• Extension Number
• Registration Name
• Registration Password

Transport protocol

Open the same extension and go to Advanced > VoIP Settings > Transport to see which SIP transport the extension uses (UDP, TCP, or TLS). In this example the extension is set to UDP (User Datagram Protocol).

Note

• If the extension uses TCP (Transmission Control Protocol), confirm the SIP TCP port is enabled on the PBX, otherwise registration fails. You can check this under PBX Settings > SIP Settings > General > Basic.

  

• If the extension uses TLS (Transport Layer Security), confirm TLS is enabled on the PBX, otherwise registration fails. You can check this under PBX Settings > SIP Settings > TLS.

  

PBX domain name

Note the domain name of your PBX (Private Branch Exchange, the phone system your extensions register to). This example uses pbx.example.cloudvoice.com.

SIP registration port

The SIP registration port is 5060.

Step 2. Register the extension on the Grandstream phone

1. Sign in to the phone’s web interface.

   

   a. Enter the phone’s IP address in your browser’s address bar.

   b. Enter the username admin and its password.

   c. Click Login.

2. In the left navigation bar, go to Accounts > Accounts and choose an account that is not in use.

   

3. On the General Settings tab, fill in the registration fields using the values from Step 1.

   

   • Account Active: Select the checkbox to turn the account on.
   • Account Name: Enter a label for the account. This name appears on the phone’s screen.
   • SIP Server: Enter your PBX domain name followed by the SIP registration port.
   • SIP User ID: Enter the extension number.
   • SIP Authentication ID: Enter the extension’s registration name.
   • SIP Authentication Password: Enter the extension’s registration password.

   Tip

   Enter SIP Server as the domain name and port together, joined by a colon, for example pbx.example.cloudvoice.com:5060.

4. Open the Codec Settings tab and remove any codecs you don’t need for this account.

   Caution

   Grandstream phones enable every available codec on an account by default, which can cause problems with outgoing calls. Trim the codec list down for the account you registered against the Cloud Voice extension.

   

5. Click Save and Apply.

Result

The extension is now registered. To confirm, open Status > Account Status in the phone’s web interface and check that the account shows as registered.

Tip

If the account does not register, re-check that SIP User ID, SIP Authentication ID, and SIP Authentication Password exactly match the extension number, registration name, and registration password from Step 1. If the extension uses TCP or TLS, also confirm the matching port is enabled on the PBX (see the note in Step 1).
