Broadband, voice and data distributor DMSL has extended its BT Business contract through to 2013.
The two firms have been doing business for over 10 years, in which time DMSL claims to have signed more than 30,000 BT Business contracts.
Besides its broadband offerings, DMSL is now looking to grow sales of BT's BTnet leased line services, which offer improved bandwidth to business customers.
Said DMSL managing director John Carter: "We believe there is even more potential here. Many more organisations are now making use of the web to link offices, run VPNs and enable home working.
"Demand for dedicated bandwidth is going to grow," he added.
It is also planning a renewed customer recruitment drive, trading off BT's reputation in the small business market.
