Comptel has announced that the number of telecom subscribers served by Comptel Solutions through its customers has now reached close to 200 mn. This landmark has been achieved through a combination of signing of new customers in 2007 and the phenomenal growth of the existing customers. Comptel has achieved a considerable degree of success on the Indian subcontinent in recent years. Many leading service providers in the region are Comptel's customers.

The sheer size and speed of growth of the subscriber base create unique challenges at the OSS level.
