Hello, all! I've noticed a peculiar situation and I am hoping someone can shed some light on it for me. We have an Asterisk (1.4.18 ) box talking to the world via Zaptel on a PRI from a telco (USA). I have an extension that returns busy signal (fast-busy or regular busy) (using US tones). When I call from a landline or from another PBX, I get a busy signal, just like I expect. But when I call from a cell phone, the cell phone terminates the call as soon as connection is established. I've tested several cell phone models from different providers in the US. Same thing happens with calls coming from Gizmo.
I manually changed the tones I send back (with Playtones) to mimic Austrian busy tone (picked the first one in the list from indications.conf) . Now, from the cell phone and Gizmo alike, I get busy tones. So, my questions is: why do cell phones and Gizmo both detect busy tones and terminate the call? Is that a standard behavior? Why don't landlines do that? Thank you in advance.
