Cisco took the top spot for the dollar value share of all proposals written by solution providers in the first half of 2008, raking in an average transaction size of $30,500 with the total value of proposals reaching $907 million. That sizeable number of transactions in the first half of 2008 gave Cisco a 26.6 percent share of the value of all SMB unified communications proposals written. Cisco's closest competitor, IBM with its Lotus suite, only reached $511 million, or 15 percent dollar value share, despite having a higher average transaction size of $40,800. Rounding out the top five were HP, Alcatel-Lucent and 3Com, which offered the highest average transaction value with $81,800 per proposal.
