When you are looking for a VoIP provider for your business in Spain, there are some things you need to consider. Choosing the VoIP provider is crucial for your business. Here are the things you should check before you sign up with a VoIP provider.

• CNMC-aligned number registration: Spain has strict rules when it comes to telecom. Your VoIP provider should take care of the registration process for you.

• Local city number availability: It is okay to have a number but if you are targeting customers in a specific city like Madrid or Barcelona you need a local area code. Make sure your VoIP provider has numbers for the cities you need.

• HD call quality: If the audio quality is poor it can damage the trust between you and your customers quickly. You should check that your VoIP provider has coverage inside Spain. They should not be routing calls through countries before they reach your customers.

• IVR and smart call routing: Every time a customer calls they should be able to reach the person without being transferred multiple times and put on hold. A good IVR system can handle this automatically.

• Call recording: You need to be able to record calls for training your team checking the quality of service and following the rules for business communication in Spain.

• Real-time analytics: You should be able to see how your team is performing at any given time not in a report you get later.

• CRM integration: Every call should be logged automatically in your CRM system. Whether you use Zoho, HubSpot, Freshworks or Pipedrive your VoIP platform should be able to connect with it

• Mobile and desktop apps: Your team should be able to answer calls from anywhere whether they are using a laptop in London or a phone in Dubai. The device and location should not limit your team.

• 24/7 customer support: Your phone system is not just for use during business hours. If something goes wrong at midnight you need to be able to get help right away.

• Number portability: If you already have a number you should be able to bring it with you to your new VoIP provider without disrupting your service to your customers.
