I trying to receive a SIP call and have ring a analog phone. I have a TDM11B card with FXS(green) module in line 1. I have Sip server "SER" setup to accept a SIP call, add a 970 extension to uri and set to asterisk SIP server on port 5065. When I send a SIP call from "kphone a soft SIP phone" running to sip://wally.world@cci.net "SER" picks call ok and changes uri to sip://9703653113@cci.net before relaying it to asterisk. Asterisk does pickup the SIP call OK errors with Everyone is busy/congested. Specfically the output from output from /usr/sbin/asterisk -vvv -c: -- Executing SetCallerID("SIP/cci.net-08619b08", "sip:bob m<0000000001>") in new stack -- Executing Dial("SIP/cci.net-08619b08", "Zap/1|20") in new stack Feb 3 09:54:57 NOTICE[-182760528]: app_dial.c:743 dial_exec: Unable to create channel of type 'Zap' == Everyone is busy/congested at this time -- Executing Hangup("SIP/cci.net-08619b08", "") in new stack == Spawn extension (default, 9703653113, 3) exited non-zero on 'SIP/cci.net-08619b08' I suspect the error is in my configuration here is copy of my confiuration files.
