<div>Hello My Friends,</div>
<div> </div>
<div>I have a problem about the PRI E1 QSIG connection between my 2811 VGW and Alcatel 4400 PBX. When the analog phone behind the PBX tries to call to the ip phone that is located at the remote side where the CCM is there, the analog phone still gets the continuous dial tone although caller dials the extension number. During the dialing time there is no dial-tone, there is silence in a normal way but after dialing the extension, caller starts to get dial-tone again. I realize that for each extension that caller dials without on-hook the phone, one b channel is assigned to that call but still there is dial-tone, there is no ring back tone. After the caller dials the extension, he or she still gets dial-tone and without on-hook the phone, the caller dials another extension over the same dial-tone, another bchan is assigned to that call but still there is no ring back tone and still there is dial tone. After the specific amount of time, the caller gets the fast-busy tone in a normal way. When I used sh isdn active command during the dialing time, I see the call. What I should do? Could you help me?
