Customer notification: Closure of 118 909 Directory Service

The cost of providing 118 Directory Services has risen considerably over the past few years based on a reduction in demand for these services and the availability of low cost or free services via the Internet. As a result of recent commercial changes from our Directory Services partners we were faced with having to make a decision either to substantially increase the cost of using our 118 909 service from 1st January or closing the service down and we have therefore regrettably decided to withdraw the service as of Friday 6th January 2017. We would like to thank all past users of 118 909 and should any customers need any assistance regarding the withdrawal of this service please do not hesitate to contact us at or on 0344 871 1122 option 2 and we will be happy to assist.

Making the move to SIP?

Many of our customers are turning to SIP trunks as an alternative to ISDN30. SIP delivers a more cost effective, flexible voice solution that can support the more complex requirements of unified communications.

We deliver highly flexible SIP solutions which are compatible with all the leading IP PBX brands in the UK market. Our SIP services are more cost effective and flexible in terms of what telephone numbers you can have and the locations in which you can have them. They are quick to install and offer business continuity to ensure that your business never loses a call.

Delivered as a managed service, Maintel’s SIP solution includes the IP connectivity, SIP trunks, number management and Sessions Border Controllers (SBCs).
