VoIP MSP's & government [sub]contracts

Hi Searchfunders,

Does anyone have experience evaluating VoIP-specific MSP's that would be willing to share their insights? I'm seeking to better understand Avaya-based technology tailwinds/headwinds and how VoIP-focused MSP's fall into the broader MSP ecosystem (valuation, consolidation potential, competition etc..).

Additionally, the business I am looking at has 10+ year sub-contracts in place with large federal agencies, but from my initial diligence it seems that these contracts are reevaluated on an annual basis for renewal. Are there any anecdotes as to the likelihood of government contracts getting renewed each year once a long-term agreement is in place? I assume each contract / service has its own idiosyncrasies, but would love any color on what to look out for.

Thanks in advance for the help!
