What Are the Benefits of a SIP Proxy Server?
A SIP proxy server can also be configured as a stateful SIP server. This means that it will keep records of all conversations on it.
- A SIP Proxy can also act as a registrar server. A registrar is a service that identifies and authenticates users within a SIP network.
- There are two types of registrar: static registration and dynamic registration.
- A static registration will send traffic to a single IP address, and dynamic registration will use a domain or IP address.
- A SIP proxy server will handle security on your behalf.
- It will check the caller’s identity, if necessary, and will be responsible for encrypting the data. SIP servers also provide security for other users.
- For example, a SIP proxy can prevent fraudulent activity.
- The server will block calls when an individual does not have enough balance.

A SIP proxy can even protect the caller’s credit and ensure that the caller is authorized. SIP proxy servers have two significant functions. They allow companies to answer inbound calls quickly, and incoming calls can be forwarded to several SIP phones.
