Hello All, I just started to use asterisk with Digium card (4 fxo ports) and I've met some problems ( I'm just new in asterisk so questions may be stupid ) my environment: Debian testing, asterisk 1.0.9 zaptel-1.0.9 TDM04P 1) when asterisk receiving incoming call on TDM card all networking cards stops to send or receive any data for some time nothing suspicious in the log files, nothing in dmesg ( even with highest level of logging) I was suspected shared interrupts - but ethernet and tdm cards are using different ones any ideas ? 2) does someone has simple example config files for using asterisk as a gateway between SIP/internal extensions and PSTN ? 3) I've set up fax receiving and sending it to email [fax] exten => 1,1,Macro(faxreceive) exten => h,1,System(/var/lib/asterisk/mailfax "${CALLERIDNUM}" "${CALLEDFAX}" "${EXTNAME}" "${EXTMAIL}" "${FAXFILE}" "${EXTCOMPANY}") but CALLERIDNUM always empty any suggestions ? P.S. I'm not expecting answers with full sescriptions if my questoins are already answered - just give me the link to this page.
