Value Sourcing Group

All contract negotiations performed by VSG are led by a senior member of our staff with an average of over twelve (12) years of telecom carrier contract negotiations experience. Each client engagement is supported by experienced telecommunications analysts providing valuable and industry-leading reports, analysis and evaluation tools. VSG network design professionals play an important role in providing assistance pre, during and post sourcing engagements involving frame to MPLS transition, VoIP deployment, SP trunking or other network architecture design and analysis considerations.


VSG consultants have saved their clients over $500M in network services expenses. History has proven an experienced consultant-led team will obtain 15% to 20% more cost savings than clients may hope to achieve without professional third party support.


Recent contract negotiations engagements led by VSG senior negotiators with major corporations have produced the following results:

  • 53% annual savings on voice and conferencing services
  • 58% or $11M savings over the life of a three year contract
  • 42% annual savings for voice/data and internet services

VSG consultants have participated in or spoken at numerous sourcing events, including the Sourcing Interest Group (SIG) and Society of Telecommunications Consultants (STC) and have authored several white papers including “Telecommunications Contract Negotiation is Not Rocket Science – It is Far More Complex!”
