Hi I have been running my UC320 with out fault for a while but the call forwarding fuction has stopped working correctly
If I put call forwarding on to call my mobile number and then call the DID Sip line number for that extention it drops the call with out ringing. but all other DID's etc continue to function correcly. it only call forwards if you dial it from another customer who has the same SIP provider but from a BT line it's dead..... I have logged the issue with VoIP Unlimited to see if they can give me any ideas but it has left me stumpt. as I have re built the box three times tonight.
