With a full range of telecommunications services and competitive tariffs, Maximum Group can arrange the installation of new telephone lines or the transfer of existing services. Making everything quick and easy for business operations, Maximum Group is your one-stop-shop when it comes to network solutions in Birmingham and across the UK.
We can install and maintain:
- allow one incoming or outgoing call at any one time, for voice calls, fax or broadband.
– for a collection of analogue lines on the same number, usually connected to a phone system and allowing more concurrent calls.
ISDN2 is a 2-channel digital line that can be used for voice, data, video or fax, and can allocate separate phone numbers to users.
ISDN30 is like ISDN2 but supports between 8 and 30 channels.
SIP Trunks are IP phone lines; a modern alternative to ISDN lines. SIP trunks are more preferable due to being cost-effective and installed at a fraction of the time and cost of ISDN.
