Echo Issues When Transferring Calls


Running TrixBox v2.2 on capable Dell hardware. Snom 360 phones.

Whenever an inbound calls comes in over our IAX connection and is manually transferred, a terrible echo ensues 80% of the time. I assume this has nothing to do with our ZapTel cards since this is not for analog inbound calls. Strictly inbounds from our VOIP provider, so I haven’t messed with the echo cancellation settings for the card.

There is plenty of memory and CPU available.

If calls are not transferred, there is no echo. Just when transfers occur.

Anyone else have these issues?
