hi there is one way audio in the calls generated or originated from the cme's phone, the physical connection is through an E1, and this problem also happens with a FXO port. I think that something is happening with dsp, what do you think?

i sincronized the wic where the E1 is located with the internal clock of the router, and the show voice dsp voice, i see there are a lot of resources.


I have this problem too.

Hi, verify if "h323-gateway voip bind srcaddr ip address" in configured on the interface you are using for signaling in your voice gateway, also vevrify if you have configured this command: "voice rtp send-recv" in your router.

Hope this help
