Described is a method for performance estimation of a communication device. The method comprises: executing active probing to determine active probing data; reading operational data which includes data related to channel and its noise condition, latency and counter values related to user data traffic between the communication device and another communication device, wherein the operational data is relevant to the current settings of the communication device; and training a performance estimation algorithm for the communication device according to the active probing data and the operational data.

A system and method for enabling the telephone number as a platform for the association of IP-enabled services with legacy telephone service. A unified services enabler platform may be utilized to associate a customer and their telephone number with a variety of services and applications from multiple different ecosystems. The customer can continue to use their existing telephone service and in addition can utilize new IP-enabled features that are associated with their telephone number as the common ID.

A channel-based voice call method, including: accepting a matching request of a client, acquiring a matching result of the client from a matching pool, and returning the matching result to the client; and acquiring a call matching acceptance instruction of the client, allocating a temporary channel and locking the temporary channel, and sending a successfully accepted matching message, a temporary channel number and a channel password to the client, such that the client enters the temporary channel based on the successfully accepted matching message, the temporary channel number and the channel password to make a call.

A method is presented of determining whether a digital subscriber line is susceptible to radio frequency interference. The method measures the signal to noise ratio (SNR) margin on the digital subscriber line over a number of 24 hour periods. The measured SNR margin over a given 24 hour period is then compared to a reference function of SNR margin over time (24 hours), where the SNR margin of the reference function is higher during the day and lower during the night, and also repeats daily. A measure of the interference susceptibility is generated based on the degree of similarity between the measured SNR margin and the reference function.
