I have noticed someting weird…
I have on my PBX, the possibility to dial some extension during the speech of the IVR.
On some phone, that work fine… Asterisk will catch and accept the key pressed.
On some other phones, you can dial as much as you want, it will never catch any keys at all … !!!
Any idea why ?
Is that a DTMF config problem ? (Usually I have rfc…)
Thanks for your help
