Hi I have a Panasonic TDA600 conected with one E1 to the pstn and one PRI with my Asterisk using a Digium <SPAN class=Product>TE220B card.</SPAN><BR>
<SPAN class=Product>The Panasonic is master clock and Asterisk is slave, additionally the Panasonic takes the clock from the PSTN E1. This scheme works and I´m able to make and receive calls the problem is that some times the Asterisk lose the synchronism with the Panasonic and the log shows this error: </SPAN><BR>
