Configure a Grandstream phone with a SIP account
How to register a Grandstream phone on a Vohippo SIP account from the phone's web interface. All you need is the phone's IP address and the account's username and password, which you find in the portal.
How do I open the phone's web interface?
On Grandstream phones the IP address is shown in the status or network menu. Open it in the browser and sign in as admin: on recent models the default password is printed on the label.
- The phone and the computer must be on the same network
- Type the phone's IP address into the browser, for example http://192.168.1.50
- If the default password does not work, check the phone's label or the model's manual
Which fields do I fill in?
The path is Account → General Settings. Fill in the fields like this, with your SIP account details:
- Account Active: Yes
- Account Name and Name: the name to show
- SIP Server: sip.vohippo.com
- SIP User ID: the SIP account's username
- Authenticate ID: the same username
- Authenticate Password: the account's password
SIP account on the phone
Username and password are in the portal: one account per phone, with its own channels and limits.
- Server sip.vohippo.com, port 5060 UDP
- Username and password of the SIP account
- Codecs G.711 a-law, µ-law and G.722
How do I check that it is registered?
Save and wait a few seconds. The account status shows on the web interface's status page and, usually, on the phone's display.
- Registered status: the account is live, you can make a test call
- In the portal, under SIP accounts, the account shows as registered
- Call a mobile phone: if you hear and are heard, you are done
What to know about Grandstream phones
Menu items can change slightly between models and firmware versions: if a field is missing, look for the one with the same meaning.
- Each account on the phone has its own pages: General Settings, Network Settings, SIP Settings, Codec Settings
- The number of accounts depends on the model
- The registration status shows on the accounts status page
If something goes wrong
The problems are almost always the same on every brand: they are explained in full in the general VoIP phone guide.
- Registration rejected (403): wrong username or password, often a trailing space copied by mistake
- Registration that comes and goes: expiry too long behind a router that closes ports, try 300-600 seconds
- One-way audio: almost always NAT, turn off the router's SIP ALG
Frequently asked questions
Are SIP User ID and Authenticate ID the same?
With Vohippo, yes: both hold the SIP account's username.
The phone cannot find the server: what do I check?
That the SIP Server field holds only sip.vohippo.com, with no http:// and no spaces, and that the phone has working DNS.
