5 Ways You Can Successfully Implement SIP

Voice over IP (VoIP) uses Session Initiation Protocol (SIP) to convert voice to data and transmit those data over public or private IP networks. Businesses have used VoIP as a way to cut costs, add features and capabilities, and make more efficient use of their IP networks. Here are five methods you can research and use to make this process even better.

1. Service Provider
Find out if your service provider owns its own physical delivery methods for secure end-to-end service. Carriers that patch multiple networks together (some of which may not include SIP) may cause issues in quality of service. When troubleshooting multiple networks, it can take longer to diagnose issues and delay issue resolution. Carriers that have a native SIP network are ideal because such a network is a more efficient way to deliver IP traffic.

2. Advanced Features
To gain the most out of SIP, ask your service provider if it has a business continuity and disaster recovery plan. Your provider should have a failsafe plan in the event of outages on its end to ensure that emergency calls go through at any time. No service provider should ever charge for E-911 service. When properly managed, local emergency dispatchers should be able to find a caller’s location in the same amount of time as a 911 call.

3. Convergence
When researching a VoIP provider, ensure that your IT engineers and service provider can work together to design an efficient SIP network. Most service providers already have a plan or have experience working with companies that have on-premises data networkers. Each solution may be unique based on the needs of the individual business, but many service providers are more than well equipped to handle this. If you plan to grow your business or have already experienced significant growth, your telephony plan should be scalable to meet your business needs.

4. Security
When securing a VoIP solution, firewalls and other devices should be sufficient to provide adequate security. Some networks use a session border controller (SBC) device for traffic control, additional security, and configuration. If you use both a firewall and an SBC, your firewall should be placed outside your network as a first line of defense for all network traffic. Your service provider should offer SIP registration on the SIP trunk.

5. Redundancy
You have the option to centralize or distribute SIP trunking. If you have a large network (more than 500 session instances), redundancy is required. Fewer than 500 sessions are a good idea but may not be required. An assessment of the impact of the event of an SIP trunk failure to a nearby backup location until service resumes may be necessary. Your service provider will be able to provide the details on its end. If an SIP trunk goes down, outbound calls should be routed seamlessly through a traditional public switched telephone network gateway. Inbound traffic alternates should be offered through any service provider.
