I experience every time I have FXO with H323 gateway register to CCM, but never ask why.
VIC2-2FXO with H323 gateway register to CCM4.13. FXO has plar command point to IP Phone extension 1234.
If I call the phone number FXO (212 424 1234) from my cell phone. I will hear ring back tone twice, sometimes 3 times before I hear IP Phone ring.
Is that normal?? Is there any command or method to fix this kind of problem??
