I have a freepbx system with sangoma E1 card without Echo Cancellation. How can I enable software Echo Cancellation in freepbx
you may try from gui for card setting.
there are no settings . can you specify which settings
maybe check with this:
. if there are some software options, you may select one you need.
From my experience, the build-in software AEC does not always work well. For example when the echo tail exceeds some minimum threshold or there is some volatility in the echo path, the build-in software AEC breaks. If you find out that this is the case in your system, then there are two options:
- Upgrade to a card with AEC.
- Use an external software AEC, like PBXMate, that will do the echo cancellation on behalf of your devices.
I’ve always been quite impressed with OSLEC software echo cncellation. But I did find on a recent FreePBX build that it was not getting enabled by default and so I added under:
‘Connectivity \ DAHDI Config \ System Settings’ a new variable (Other Dahdi System Settings:)
‘echocanceller’ = ‘oslec,1-31’
These settings were for a Sangoma ISDN PRI card with no hardware cancellation.
thanks let me check this
