[Spce-user] Call forwarding issue

Tue Nov 20 14:44:21 EST 2012

I am experiencing a problem with call forwarding.  I have a line 318396xxxx
that is call forwarded to 318537xxxx which is an external cell phone.  When
someone calls the 396xxxx number it rings the 537 number.  The call is
answered by the 537 and audio works fine.  At 30 seconds the call is
dropped on the 537 number.  To the person calling the 396 number it does
not drop, it just starts ringing and is connected to the 537 number again.
 At this point the call works fine.  Any help would be greatly appreciated.
