Then configure your outbound dialplan like this: exten => outboundexten,1,Dial(SIP/...) exten => outboundexten,n,Dial(DAHDI/...) If the SIP is up, the call goes through on that Dial statement. When the call is over and the people hangup, it will not continue down to the next line. If it's down (and the system knows this because of qualify), it will fail and automatically roll to the next line. I've used this to setup failover between DAHDI and SIP a few times. -- Thanks, --Warren Selby, dCAP http://www.selbytech.com Another thing to check is Congestion, sometimes my Sip Provider works fine, but for some reason there end peer has failed. exten => s,n,Dial(SIP/xxx...@providerx) exten => s,n,GotoIf($["${DIALSTATUS}" = "CONGESTION"]?ProviderXCongestion) exten => s,n,Hangup() exten => s,n(ProviderXCongestion),Dial(IAX2/XXXXX/XXXXX) exten => s,n,GotoIf($["${DIALSTATUS}" = "CONGESTION"]?ProviderYCongestion) exten => s,n,Hangup() exten => s,n(ProviderYCongestion),Dial(DAHDI/XXX/XXXXXX) exten => s,n,Hangup()
