SIP Trunking

VoIP phone system

ISDN services can be expensive and inflexible; however until recently ISDN has been the only viable method of providing business grade telephone lines to a PBX.

Infinitel’s SIP Trunk service creates an IP connection between your PBX and our network, allowing voice calls to be made and received over a data connection, significantly reducing your charges.

If you have a traditional non-IP PBX and would like to extend the life of your hardware, we can implement a gateway solution to enable SIP Trunking without any changes to your existing hardware.
If you already have a SIP-enabled IP PBX with ISDN or PSTN lines, Infinitel’s SIP Trunk service can be used to replace or complement the existing connectivity, allowing you to terminate your voice calls over the public telephone network at a considerably reduced cost.
 Using SIP Trunks in this way can provide cost effective telephone service to your offices or individual users in remote locations, such as homeworkers.
 Reduce line costs Save thousands of pounds in line rental with little or no upfront capital expenditure.

Reduce call costs Save on national and international voice traffic without complicated discount structure or long term commitment.

Mark Sidebottom

After having problems with a previous IP phone service provider we decided to move to Infinitel after a recommendation.  Andrew kept me informed all the way through the switch over process which was smooth and simple.  Since then Andrew has always been available to speak to and quickly rectified any teething problems we had.  I would highly recommend Infinitel for internet phone services.

We approached Infinitel with a really specific brief.  What we were looking for as a company was a particularly niche solution that really needed to work.  Andrew and his team turned this solution around with 24 hours and turned something that I had been trying to implement for over 12 months, in to a really easy and simple solution.  From start to finish, the process was easy and streamlined and has given us exactly what we are looking for as a company rather than what a company “thinks” we need.  They come highly recommended from us

Apex Computing Services has worked with Infinitel on many projects including replacing our own telephone solution in our office. We needed very specific features including reporting and monitoring of calls. We also required a whisper function that would allow us to be able to assist and prompt engineers when completing IT support calls to customers. The support we received from Infinitel was excellent and we now have a system that is fit for purpose. The system was delivered on-time, within budget and with little disruption to the business. Thank you!

Of all the suppliers to deal with, telecoms and mobile phone suppliers in my experience are the worst. When I met Andrew Platt is was clear he is someone who cares about what he does and has very high standards of customer service. The transition of Barnabus mobile phones from EE to Vodafone went very smoothly and even setting up our new phones was painless. Andrew has made our new contract easy to understand and competitively priced, so that we can show value for money to our supporters. Thank you Andrew, we never knew that mobile phone companies could be like Infinitel!

Andrew and the team consistently astound me with the speed they act whatever our demanding enquiry is!.
