I Have Grandstream HT-488 ATA (1 FXS & 1 FXO)
FXS Registered with 1998
FXO Registered with 1999
When Someone calls the PSTN Line HT-488 forwards the call to VOIP ext 888.
Now 888 welcomes the caller and then transfers to ext 1000 (Grandststream GXP2000).
All goes well.But the caller ID which Flashes is not of the caller BUt 1999 (FXO Port sip a/c).
I want to see the caller id of the caller Please Help…
