[Freeswitch-users] Choopy one-way noise

[Valer Nur]

Hi bawajan,
I have listened to the files. What I can hear is a constant stationary noise. 

Usually the origin of such noise is hardware issues (mic/cables/etc.).
If you are unable to find & fix the source of the problem, you can use noise cancellation software that will easily remove this noise.
One software that you can try is PBXMate. A usage example is available on FreeSWITCH wiki: http://wiki.freeswitch.org/wiki/PBXMate-FreeSWITCH-integration

Hi Moises Silva,

am new to freeswitch and am facing same noise issue when making call from
ISDN (freetdm) to SIP UA.

As per above mail, i have did ftdm trace and listen the clips.  I found same
noise in generated voice clip of line 2 (sip).

am attached both audio files for your reference (ISDN line 1 and SIP line
2).

Kindly let me know, what needs to do to rectify it.
