Kommersant reports that the transaction is the operator’s first major one in Moscow.
Although no financial details have been disclosed, the sale price is believed to be in the region of R1.5 billion (€21.2 million).
IHome has until now been owned by its founder and CEO Vasily Maskovsky.
It works mainly in the inter-operator market and besides having its own backbone network in Moscow and 30 other Russian cities it has traffic exchange points in eight countries around the world.
Meanwhile, Perm-based ER-Telecom is the second largest provider of broadband internet services in Russia after Rostelecom.
It is also a key player in the Russian pay-TV market but until now has not had a strong presence in Moscow.
