hi all
situation: a call comes from the pstn to an ip phone, this ip phone forward all calls back to another pstn-number outside.
in this case we have quality problems.
our gateway is an 1760 with enough dsp´s and ios 12.3.11T2.
have you any helpful debug commands or any helpful hints?
all other voice-quality was good.
P.S. if me make the same forwarding from a normal pbx installation to the same number we have no problems.
