PSTN Access Numbers and DTMF
Folks when using these access numbers here what I face:
1) I dial the PSTN access number.
2) I enter my SIP number
3) My SPA 3000 answers
After that it does not allow me to key in any other numbers such as my PIN to gain access to the dial tone of the PSTN line attached to my SPA 3000.
On the other hand if I use IPKall everything works fine.
Any suggestions?
I know the access numbers are contributions from VoIP providers but how we can fix this issue?
