Hi,

Are you using SNR or just doing Call forward all.

Try to elaborate the issue as much as possible.

It's just forwarding from the user phone.

here's the configuration under the port:

voice-port 0/1/0
trunk-group CC
supervisory disconnect dualtone mid-call
supervisory custom-cptone STC
supervisory dualtone-detect-params 1
no battery-reversal
cptone BR
timeouts initial 10
timeouts interdigit 15
timeouts call-disconnect 5
timeouts ringing 5
timeouts wait-release 5
timing hookflash-out 50

You do not have any impedance matching on the line.

The following lines are all you need under a voice-port for disconnected party in the UK. But you may have to find the disconnect tone by analyzing on a PC. 

Then

voice class custom-cptone customBBV
 dualtone disconnect
  frequency 400
  cadence continuous

and then :-

voice-port 0/2/1
 supervisory custom-cptone customBBV
 input gain 2
 cptone GB
 timeouts interdigit 6
 timeouts call-disconnect 5
 timeouts wait-release 5
 connection plar opx immediate 556
 impedance complex2

We have similar issues if the line is bad or on an old exchange or through a Voip adaptor etc.
