I have 2 analogue trunks and 3 sip trunks, 2 spa508 and an analogue telephone.
Caller ID is received on the SPA phones for ALL incoming trunks, however caller ID is not displayed on the analogue phone for ANY trunk.
Region is set to UK. The analogue (FXS) phone rings normally and in all other ways works fine.
The analogue phone WILL, however, show the caller ID if I am on a call at the time a second call is received (call waiting).
Any ideas?
Another thing is that when dialing an internal extension, the ring back tone sounds strange on FXS phone, but on SPA phones sounds normal.
Many thanks
Rich
