How do you scale and customize SIP trunking vs ISDN to meet your changing business demands and opportunities?

1 What is SIP trunking?

SIP trunking is a technology that uses the internet protocol (IP) to deliver voice and data services over a single network connection. SIP stands for session initiation protocol, which is a standard for initiating, managing, and terminating multimedia sessions. A SIP trunk is a virtual link between your IP-based phone system (also known as a private branch exchange or PBX) and the PSTN. SIP trunking allows you to make and receive calls from any device that supports IP, such as desk phones, mobile phones, laptops, or tablets.

2 What is ISDN?

ISDN stands for integrated services digital network, which is a legacy technology that uses digital circuits to transmit voice and data over copper wires. ISDN was developed in the 1980s as an alternative to analog phone lines, and it offers higher quality and faster transmission than traditional phone lines. An ISDN line consists of multiple channels that can be used for different purposes, such as voice, fax, or video. An ISDN line connects your PBX to the PSTN via a physical cable.

4 How customizable is SIP trunking vs ISDN?

Another benefit of SIP trunking over ISDN is its customization. With SIP trunking, you can tailor your communication system to your specific needs and preferences, such as choosing your own phone numbers, caller ID, call routing, call recording, voicemail, conferencing, and more. You can also integrate SIP trunking with other applications and platforms, such as customer relationship management (CRM), email, chat, and web conferencing, to enhance your productivity and customer service.

With ISDN, you are restricted by the features and options that your provider offers. You may have to pay extra for some features, such as caller ID, call forwarding, or call waiting. You may also have difficulty integrating ISDN with other applications and platforms, as ISDN is not compatible with IP-based technologies.

5 What features does SIP trunking vs ISDN offer?

SIP trunking and ISDN both offer basic features like making and receiving calls, transferring calls, holding calls, and dialing extensions. However, SIP trunking has additional advantages over ISDN such as unified communications, disaster recovery, security, and mobility. Unified communications allow you to communicate with customers and colleagues using different modes and devices. Disaster recovery allows you to reroute your calls in case of power outages or network failures. Security is ensured through encryption and authentication protocols. Mobility enables you to make and receive calls from anywhere with internet access using your mobile phone or laptop.
