hi, I have some problem with outgoing calls without callerid. If I don't set caller id (callerid is empty) call is droped. Message I get form asterisk: chan_ss7.c:3523 monitor_main: ISUP decoding error, message discarded. (typ=3) Any idea why? I think it's problem with signalling but have no idea how to resolve it.
