Two things here:
First a margin call by definition is just that, a call to the client to put more money into their margin account. Both security firms and futures firms do this. And yes sometimes they make a 100 calls a day to different clients about their margin accounts. Generally and depending on the client the broker makes the call before the position has hit its maintance margin limit. A lot of futures, equity brokers depending on the client, the asset being traded and the company agreement will give the client a day sometime two to make a wire.
Second, the reason this is different in the FX Market is because the market is much more volatile and instead of clients having 50% margin in the equities world they have 1% margin with FX. Leverage and Volatility are the two biggest reasons FX firms dont do this, they do not have the time to give clients a day or two. However, depending on the clients relationship with their FX broker some brokers do make actual calls to the client. Those clients are generally ECP's or member firms.
