How to Configure a SIP Account

After signing up with CommPeak and getting your SIP account credentials, your next step is registering your SIP account in CommPeak Softphone, a third-party application, or with your IP phone to make your first call.

👍
TIP
You can also use the built-in CommPeak Softphone with your JWT-enabled SIP accounts to place calls right from your browser. You can read more in the Built-in Softphone for JWT-Enabled SIP Accounts article.

👍
TIP
With CommPeak Softphone, you get an enterprise-level tool without installing any third-party software.

❗️
IMPORTANT
If you're using third-party SIP clients (not CommPeak's Softphone), you must manually enable SRTP (Secure Real-Time Transport Protocol) when using TLS for SIP transport. This ensures media encryption and compatibility.
