FXS idle problem

Hi:

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.

regards

Re: FXS idle problem

Conditions: With caller-id enable configured on FXO ports, the call will connect, but no audio is heard. When this occurs, the following error message can be seen at debug level:

Jun 20 01:41:15.855: mbrd_e1t1_vic_connect: setup failed

Jun 20 01:41:15.855: flex_dsprm_tdm_xconn: voice-port(0/0/1), dsp_channel (/0/2/0)

Workaround: Disable caller id on the voice-port.

Re: FXS idle problem

thanks for answer

but, if in the FXS port doesn't have a caller-id enable command, what is the reason of this message.
