In general, in one aspect, a computer-implemented method for establishing multiple communication channels between a service provider and a consumer includes establishing a text based communication between the consumer and the service provider over the Internet. The method also includes receiving, at a central system, a first telephone number provided by the consumer via a first user interface and a second telephone number provided by the service provider via a second user interface. The method also includes calling, from the central system, the first telephone number and the second telephone number and bridging the calls between the central system and the first telephone number and the central system and the second telephone number to establish a communication channel between the service provider and the consumer.
