Thanks by your answer Moises.<br><br>I have 2 E1s connected to a Siemens EMS 601 and 2E1s connected to the telco.<br><br>When somebody was trying to dial a pstn number from the siemens side, he/she had to dial quickly, otherwise the call is attempted with incomplete DNIS.<br>
<br>I set <b>timers.mf_back_cycle=15000</b> and now I can wait 15 seconds between each dialed digit. So, problem solved.<br><br>Now I'm facing another one.<br><br>I can't call Siemens operators. The Siemens technician says the PBX sends a B11 when trying to call an operator and this generates an Invalid MultiFrequency Tone Error on Asterisk CLI.<br>
I got an Invalid MultiFrequency Tone Error also when I try to call to a busy extension on the siemens side.<br><br><br>This is the log of a call to a Siemens operator extension.<br><br>[Aug 25 12:19:34] VERBOSE[4206] pbx.c: -- Executing [*34902@admin:2] Dial("SIP/5001-00000013", "DAHDI/g2/4902,,rtTW") in new stack<br>
