I am working with a 2801 series with 12.4(3i) version, this equipment is interacting with a CCM5.
When qe want to use the fax ports(FXS), it works for a while but suddenly it stop to work with no reason, when we hang up the fax (off-hook) there is no tone.
in the router appears this message:
flex_dsprm_tdm_xconn: voice-port(0/0/1), dsp_channel(/0/0/0)
is anybody know how to fix it. I found a bug similar that it but with FXO and i dont use caller-id enable.
