Jajah Direct is giving their users an hour of free calling between 24 December at midnight GMT and 25 December at 11:59pm GMT. That's almost two days to take advantage of this great offer. More details on the Jajah blog.

If the free PSTN calling days that Free World Dialup used to have back in the day are any indication, I suspect Jajah's switches will be busy connecting calls. But I do have to wonder, though: how many people will sign up for Jajah Direct just to take advantage of this offer and then never use the service again? That's the problem with giving stuff away: very few people actually convert to a paying customer.
