I have a box with a TDM410P card with 3 FXS ports. It’s installed and is working fine. I can receive calls in Asterisk and do to them as I wish in my dialplan. One wish is to forward the call over an IAX trunk to another Asterisk box and then dial a SIP phone at the other end.
Some times the call is placed over the trunk but when I pick up at the other end there is nothing but a loud horrible buzzing, distorted sound. When this happens I get this in my logs…
Other times the call doesn’t even make it and I see this in my logs…
I think it all stems from this error which I always get at startup…
Does anyone have any ideas about how I can fix this?
No, but I didn’t want to call it explicitly because I didn’t think that was the way to do it. I thought it would of been loaded by the dahdi module or something.
Loaded dahdi_transcode through a simple modprobe call in /etc/rc.modules.
