PSTN Access numbers and my DTMF
I have an SPA 3000. I register it with FWD. I also use IPKall number to access my SPA 3000. When dial my IPKall number and gain access to my SPA 3000 through the FWD I can enter my PIN and have access to the PSTN line connected to my SPA 3000.
When I use the PSTN access numbers to dial my FWD account, the DTMF is not recognized and I cannot gain access the PSTN line connected to the SPA 3000. This applies almost to all PSTN access numbers.
Can anyone tell me what to do?
