Setting up a Grandstream GRP2615 with VOIP.ms

Note:

• If you want to use the BLF feature, you will need to contact voip.ms support and request that they activate it for the server that you are using.
• If you are going to be using an incoming DID number, you must ensure it's setup in the DID's settings to forward to the server you are going to be connecting to.
• These instructions setup encrypted SIP traffic. You will want to ensure that this is activated in your sub-account advanced settings.
• I am starting out with a phone running firmware 1.0.9.135 and starting from a clean factory default.

What you need to get started

To get started, you will need the following:

• A Grandstream GRP2615 IP Phone
• Valid login credentials for a voip.ms account or sub account
• The server you want to use (I'll be using toronto2.voip.ms here)

You will also need to know the IP address if your phone. The phone by default will pull an IP address via DHCP. To check the IP address of your phone you:

1. Press the center hat button
2. Select "Status" (or press 2)
3. Select "Network Status"
4. Find the IP address the phone us using (I'll be using 10.1.10.137 in my example here)

Connecting to the phone

Connect to the phone via browser of your choice. If this is the first time you have logged into the phone, you will be prompted to update the password. The default username/password are both admin.

Note: The default admin password will be on the sticker below the IP Phone.

After the login, the system will ask you to change the default password.

Updating Phone Settings

The following are the settings that need to be updated.

General Settings

Go to Accounts -> Account 1 -> General Settings

These are the settings changed from their default values:

• Account Name - Name that will be displayed for the account on the phone's screen
• SIP Server - Network address of the voip.ms SIP server you will connect to
• BLF Server - Network address of the BLF server you will connect to (This is optional, but if used should be the same as your SIP Server)
• SIP User ID - Username from your voip.ms Sub Accounts page
• Authenticate ID - Username from your voip.ms Sub Accounts page (same as SIP User ID)
• Authenticate Password - Password from your voip.ms Sub Accounts page
• Name - Caller ID Display Name (See the requirements below) (Enter it here, but it will likely be overwritten by settings in your account)

IMPORTANT for Name/Display Name field (Outbound callerID Name):
  - We suggest entering your outbound Caller ID Name must be in capital letters. This will appears more clearly/visible on some devices.
  - You must NOT use any special characters, they will not be displayed. 
  - Enter a max of 15 characters. Some of regular Canadian providers will not show more than 15 characters max. We suggest shrinking or adapt your caller ID. 
  - Spaces are allowed in a caller id name.

Additional Note for TLS/SRTP

If you want to enable the TLS SRTP call encryption, change these values:

Go to Accounts -> Account 1 -> General Settings

Go to Accounts -> Account 1 -> SIP Settings -> Basic Settings

• Use Actual Ephemeral Port in Contact with TCP/TLS - Select "Yes" (This is important for Secure SIP to work)

Go to Accounts -> Account 1 -> Audio Settings
