I’ve found the solution:
Asterisk has to be restarted, not just reloaded after zapata.conf modifications.
I’m trying to change DTMF tone duration length when I use the Asterisk Manager function “PlayDtmf”. I tried to add toneduration=600 in both sip.conf and zapata.conf and it doesn’t work, the tone duration is still very short.
Do you have an idea ?
Thanks and Happy new year !
