Om Malik posted yesterday that Yahoo will release a new version of its Messenger IM program next week that will now support calling out to the PSTN. The pricing structure hasn’t been revealed yet, but according to Om Yahoo is looking to rain on Skype’s parade:

The pricing for the callout numbers is not certain as yet, though the current generation communicator allows unlimited incoming calls for $2.99 a month or $29.99 a year. The new offering, according to those in the know is likely to put Yahoo on an equal footing with Skype. Yahoo, clearly has designs on stealing market share from Skype.
