[Asterisk-Users] small question 3 way calling

[Anthony Law]

According to voip-info.org,

"3 way calling: Normally implemented by the phone"

I am using a Grand Stream 100 and not able to make this work. I can dial out
to 1st number then with the flash button I am able to dial out again to a
2nd number. I am not able to bind them together into 1 conversation. Is
there something I have to set on the phone config or in sip.conf??

Anyone knows?



Regards,



Anthony
