Thank you for your interested in my problems.I understand what you say but I meant that the Cisco GK and cisco GW may not be in good handshake, thus GW can’t setup the regular calls 100 percent.
Yes, About selection of GK, I will consider all of respect you said.
Have you ever use Telecount Billing or Mind CTI billing for your billing system. Which is reliable? I think Telecount haven’t been successful in their Repaid billing on Cisco equipment.What do you think about that?
