# Creating a SIP Stack

Session Initiation Protocol, more commonly known as [SIP](https://prosbcdocs.telcobridges.com/appendices/appendix-a-glossary/glossary-sip), is a signaling protocol for packet-based networks and is commonly used, along with H.323 to provide signaling for Voice over IP (VoIP) communications. You must configure SIP signaling for your system. The first step in doing so is to create a SIP stack:

<br>

1- Click SIP in the navigation panel

\
2- Click Create New Sip

<figure><img src="https://docs.telcobridges.com/w/images/c/cb/Create_New_SIP.png" alt=""><figcaption></figcaption></figure>

\
3- Create the new SIP stack:

* Verify that the box labeled Enabled is checked
* Enter a name for the stack
* Click Create

\
4- Verify that the "SipCfg was successfully created" message appears
