Hi all I have installed 1.6 stable with two zaphfc single port carts and everything seems to work fine . I am using Odicha's work and everything seems to work fine . The only problem is that one telephne connection every ten-fifteen doesnot behave correctly . I dial a number and nothing happens . I wait for more than 30 seconds . I close the phone , i redial the same number and i am connected OK. For 19-15 calls everything is working fine , incoming outgoing calls everything is ok . The same problem happens sometimes with incoming calls : there is a call after IVR we hear the phone ringing , we pickup and nothing happens . We cant hear the other side and the other side doesnot hear us . I dont now how to debug this problem . any help ?
