SIP Trunk Providers - IP Voice TalkTalk Business

* Denotes a required field

What are SIP Trunks?

By connecting your business to the phone network using the internet, SIP Trunks offer you great flexibility and even better savings. It’s highly resilient as you can switch from one channel to another to ensure there’s no interruption in your service. SIP Trunks are delivered over our Ethernet data circuits ensuring you make the most of your investment. Quality of Service (QoS) is provided, prioritising calls over your data traffic, to make sure your calls will always get connected and are crystal clear. Both spend management and auto-suspend are tools for limiting the impact of PBX fraud, helping protect your business from unnecessary or fraudulent high call spend. Unlike most SIP providers, our SIP Trunks service provides hourly and daily spend management, providing peace of mind.

An Introduction in to SIP Trunks

Datasheet

Service

When considering this service, we’ll help you work through the following questions to determine if SIP Trunks are right for you.

Do you have a compatible PBX?
Do you have an existing TalkTalk Business Ethernet data circuit or are you ordering a new one?
The number of channels you need?
Have you discussed your SIP Trunking requirements with your PBX maintainer? To deploy SIP Trunks you will need to configure your PBX which may incur additional costs and activity?
Have you discussed your SIP Trunking requirements with your LAN maintainer? You may need to deploy changes to your LAN environment (VLANs, QoS etc) to set up SIP Trunks?
Do you know how much bandwidth you want to allocate to your data service (i.e. internet access) on the data circuit (this will impact the number of channels you need)?
Do you require disaster recovery, and if so what type do you require?
Do you require a bundled or Pay As You Go tariff?
