Hello list, I try to configure auto dial from asterisk (called server B) to another asterisk (server A) using SIP but I have a strange problem ! (Softphone connected to server B calling clients of server A works) On server B, I have : sip.conf : [to_serverA] type=peer username=from_serverB fromdomain=domainB fromuser=from_serverB host=server_A_IP secret=xxxx insecure=very nat=no test.call Channel: SIP/to_serverA/99123456 WaitTime: 30 RetryTime: 2 MaxRetries: 2 Context:autodial Extension:99123456 Priority:1 In plain words, I want to call server A using channel to_serverB. Server A conf: sip.conf [from_serverB] type=friend secret=xxxx host=dynamic insecure=very context=autodial nat=no extensions.conf [autodial] exten => s,1,Answer() exten => s,2,Playback(dir-intro) exten => s,3,Playback(vm-goodbye) exten => s,4,Hangup() ;and tried also to substitute s by _99XXXXXX The problem : Logs on server A show that extension autodial is called and everything seems to work! However, logs on server B says : "autodial,99123456,1 failed so falling back to exten 's' sent into invalid extension 's' in context 'default', but no invalid handler" In my opinion, the call really failed because it lasted 0 sec!!! ;-) What is my problem?? I admit that, for an auto dial, it is useless to "Playback" something! It can be replaced by a temporisation !! If you have a suggestion, help me ! Thank you!
