Establishing a network connection. In one aspect, establishing a network connection includes: establishing a connection across a first communication network that carries audio signals; encoding a computer network address for a specified network different from the first network into an encoded network address and sending the encoded network address across the first network; and using said network address to establish a network connection on said second network. In one implementation, network connectivity functionality of a computer can be automatically accessed using telephone connectivity. Out-of-band signaling provides a spontaneous network collaboration capability by sending an Internet protocol ("IP") address across a public switched telephone network ("PSTN") connection.
