Ask the provider for references and contact them to learn more about their experience. You can ask about the quality of service, support, and any issues they have experienced.

  • Key factors to consider when selecting a SIP Softswitch Vendor

  • Don’t forget to check the uptime statistics of the provider to get an idea about their track record.
  • Also, analyze the provider’s data centers and other infrastructure components. Find out what all equipment and measures they have to provide reliable services.

          2. Scalability

  • How is the solution going to handle your growing user base? Will it affect call quality and reliability?
  • What mechanisms are being deployed to avoid downtime when there is a network failure or technical fault?

          3. Flexibility:

  • Ask whether the solution can integrate with your existing applications and systems. This includes your existing business phone system and other communication apps. 
  • Does the vendor offer custom-built features and support facilities? You can also ask for custom price packages. 
  • Look into the type of features supported by the SIP softswitch. Check for call recording, IVR, conference calling, etc.

These points if checked in advance before you make any commitment can save you from a lot of surprises later. You can request a demo or trial of the provider’s softswitch to evaluate its scalability, flexibility, and ease of use in meeting your business communication needs.

  • Timely Upgradation and Maintenance

The best part of opting for a hosted softswitch is that the regular updates and upgrades, which are crucial to making the system adaptable to the current market trends, are provided by the service providers and are usually free of cost. However, if not free, you can go with the paid ones by checking their usefulness.

  • Check Set Up Time

Once you have finalized the softswitch, obviously you want to get started quickly. For this, it is important that the setup procedure of the softswitch is easy and fast.

This can be in the form of software updates or data backup services or it can simply be some customization in the software to meet business needs. Having support from a technical team is quite useful for all such activities. Therefore, check the support services to ensure that your queries are addressed immediately. It is best if it is free of cost and available 24/7.

  • Call Monitoring

Call monitoring functionality with real-time information is a useful feature. The solution must provide details of active call lists, SIP call logs, and total call monitoring which includes in-progress, concurrent, and connected calls.

  • Security and encryption

Check if the provider’s solution is compliant with industry standards and regulations.
