There are desk phones, softphones and a couple SIP trunks <br>to another office. They all experience the problem. Calls between <br>extensions, from or to the E1, from or to trunks. The only scenario <br>left to try is connecting calls only via the E1 so we completely <br>eliminate the network side of things and se if we get the same <br>behaviour. During calls you can hear some background noice and <br>interruptions in the voice. DTMF fails when we try to dial to external <br>IVR.<br><br> I do not really believe that the fault is in the Asterisk server <br>but I have to eliminate all posibilities on my side before I can lay <br>blame on the network infrastructure. I was also just wondering if DAHDI <br>would not be a better timing source for Asterisk since it is hardware based?<br><br>-- <br>Telecomunicaciones Abiertas de México S.A. de C.V.<br>Carlos Chávez<br>+52 (55)9116-91161<br><br><br>-- <br>_____________________________________________________________________<br>-- Bandwidth and Colocation Provided by http://www.api-digital.com --<br>New to Asterisk?
