Abstract: Examples to facilitate facsimile communication are described herein. In an example, on receiving a communication error for a call session, values of communication parameters to be used for another call session, which is subsequent to the call session for which the communication error is received, may be determined. The communication parameter may be, for instance, a transmission rate and an error correction mode (ECM). The values of the communication parameters in the subsequent call session may be determined, based on values of these parameters in a previous call session(s), i.e., the call session for which the communication error is received. Further, a communication channel may be established using the determined values of the communication parameters.
