(my home) The second S100I-IAXY have IP 200.253.232.23. (my office) I only obtain to establish a linking enters the two S100I-IAXY when I qualify notransfer=yes in iax.conf and I perceive a constant noise. Call of the IAXPHONE for one of the S100I-IAXY, not necessary of notransfer=yes in iax.conf and I do not listen to more the noise. Somebody can help me in the configuration of this equipment?
