Im a total new guy to The VOIP and asterisk/FreePBX world so forgive me for my ignorance.
Long story short, When my client receives an incoming call, The callers report no ring back but the call comes through and my client is able to answer. This issue recently came up and we cannot figure out what the cause is. When i call from an AT&T cell, i get a ring back, But when i use T-Mobile, Verizon, or Sprint i get no ring back. Just silence until the call is answered. Currently, When my client is called, It calls a ring group which rings all of their phones. When i set the route to ring 1 phone, We receive ring back. Any suggestions or help will be greatly appreciated.
Thank you,
Damn New Guy
So i have confirmed that a caller can hear the ringing when we set the route to a single phone and not a ring group.
Also set the send progress off as you had suggested and IT WORKED!! i had ring back from start to finish. Would you mind explaining what the send progress function is doing/does?
