mISDN/tmp channels and Quality on bridge modules

  1. core show channels
    mISDN/tmp0-u0 0123456789@external: Dialing AppDial((Outgoing Line))
    mISDN/tmp0-u2 0123456789@external: Dialing AppDial((Outgoing Line))

Why will I continue to see these channels after the call was completed?

  1. Using bridge_simple.so cause high amount of echo on the line but bridge_softmix.so doesn’t?
    Both modules are loaded but can one specify softmix to be used with mISDN?

Regards

Tested on a different system and the modules don’t seam to be the cause of the quality on the calls.

Might be going DAHDI, seams so much simpler than mISDN.
