> Hello,
> We have two asterisks 1.4 and 1.6 and IAX between them
> The second asterisk is connected to VoIP provider thru SIP.
> When I calling to conference service on some company and dialling DTMF there in some IVR menu al works fine.
> But recently we decided to upgrade that 1.4 to 1.6.2.19 or 1.8.4
> And we got issues with DTMFs after that.
> Now remote IVR is not able to detect DTMF correctly. Sometime detects wrong digits but mostly it just ignore some.
> In 5% of times when I am pushing buttons for about 1 sec and keep gap between them about 1 sec I can get success with remote IVR.
> But with 1.4.31 I can push DTMFs really fast all works perfectly.
> With 1.8.4 I even noticed that even our second asterisk on other end of IAX start having issues with detecting digits.
> All sip configs have rfc2833 dtmf mode enabled.
> I am not changing any configs after upgraded or downgrade. And it always do not work with 1.6 and working with 1.4.31
> Other strange thing that in any cases I still can see correct DTMF digits events if enabling debug on outgoing SIP channel to our SIP provider.
> Also one thing. When I am replacing IAX with SIP between asterisks then DTMS start detecting correctly with upgraded asterisk.
> So clearly something broken since 1.4.31 related to DTMF.
