Paolo, Thanks for your answer
The "show controller e1" command doesn't show alarms and neither the "show interfaces serial 1/0:15" command. the cabling is ok because when connecting the E1-PRI of the Siemens directly to the PSTN, it works, so that makes me think that the configuration of the Siemens is ok. Something strange is the word "spoofing" in the output of the "show interfaces serial 1/0:15" command. Do you think it is related with the problem i have?
I want the E1-PRI of the router to act as the PSTN side. that's why I configured the "clock source internal" and the "isdn protocol-emulate network" commands in the E1 Controller and in the serial 1/0:15 interfaces, Do you think it is correct? Can the E1-Pri of the router act as the PSTN side?
I send you the output you ask for:
