Leveraging our partners’ SIP networks means we can connect your European business to a worldwide network at a much lower cost than traditional ISDN.


Reduced Call Costs

SIP trunks can deliver cheaper international calls as they are carried out over the IP network rather than the PSTN (Public Switched Telephone Network). SIP uses an existing ISDN circuit, WMX have support for both BRI (2-channel), 2xBRI (4-channel) and PRI ISDN circuits (30-channel).


One Provider

Simplify IT and communications management workload by dealing with one supplier for all countries you operate in and serve.



Having a trusted CLI and dedicated IP address ensures that no unauthorised calls can be made via your SIP trunks. As WMX monitors your virtual lines, you can guarantee that any unusual activity will be dealt with as quickly as possible.


Complete Scalability

Global SIP is geographically independent and scalable from 1 to 10,000 users. Adding and removing users is very straight forward and does not require any site visits. Once the SIP trunks are activated, it’s easy to scale up and down as you please – the perfect solution for fast growing or seasonal businesses.



SIP lines are much easier to operate, maintain and upgrade. Controlled centrally, if a disaster occurs or staff are unable to make it into work, calls can be diverted at the click of a button.


True Resiliency & Business Continuity

SIP traffic from WMX is controlled from a central location, which means calls can be automatically diverted should disaster strike.


Business Integration

SIP allows for business integration for video applications, Computer/Telephony Integration (CTI) and Instant Messenger services like Google + and  Skype for Business. SIP trunking can act as a voice solution and a disaster recovery solution in one.


Future Proof

SIP trunking is provided over a dedicated managed WMX QOS connect and allows for future business integration for video applications, Computer/Telephony Integration (CTI) and Instant.

Leveraging our partners’ SIP networks means we can connect your European business to a worldwide network at a much lower cost than traditional ISDN.
