For some reason DTMF duration on outgoing calls (via ISDN PRI E1)
uses a super long (and totally broken duration)

[Jun 11 14:55:16] DTMF[22644] channel.c: DTMF end '1' received on SIP/542-90092058, duration 104320 ms
[Jun 11 14:55:16] DTMF[22644] channel.c: DTMF begin emulation of '1' with duration 104320 queued on SIP/542-90092058

I have tried setting the toneduration in chan_dahdi but that does not seem to help.

SIP to SIP does not do this.

DTMF detection on incoming calls unaffected

****** STEPS TO REPRODUCE ******

callan an external number that goes over chan_dahdi

I have found the cause (I think).

I had my SIP phones using DTMF via SIP info.

If I change them to DTMF via RFC2833 then the issue is no longer present.
