So the duration should be OK with versions prior to 1.8.18.0-rc1 What version of asterisk are you using? The reason I ask is that for a few releases, the DTMF acceptance duration had been extended to 4*12.75ms (or 63.5ms including 1 extra block). Again since 1.8.18.0-rc1, the defaults have been set back to Begin = 2*12.75ms and EndDTMF=3*12.75ms. They were Begin = 4 * 12.75ms and End = 4 * 12.75 These can also now (since 1.8.18.0-rc1) be set in dsp.conf as below, the values used below are also the defaults. dtmf_hits_to_begin=2 dtmf_misses_to_end=3 Alec Davis -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
