Mercury Public Affairs has signed on China’s Yealink Network Technology Co. as a client to introduce it to elected officials and policymakers in Washington.

Yealink is a top producer of video conferencing and voice communications equipment.

It teamed with Verizon Business last year to introduce the One Talk T67LTE wireless desk phone, which the partners billed as the first advanced desk phone with embedded 4G/LTE cellular technology available in the US.

Former Senator David Vitter (R-LA) and Congressman Toby Moffett (D-CT) spearhead Mercury’s Yealink team.

They are joined by Peter Kusic, who was senior sanctions policy director at the Treasury Dept.’s Office of Foreign Assets Control; Bryan Lanza, communications director for the Trump transition team; and John Lonergan, aide to ex-New York governor George Pataki.
