hi,
i am facing the "busy/congested" error while clicking the blind transfer of an internal call to a external number. here is my dialplan:
exten => _x.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _x.,2,Dial(SIP/${EXTEN}@IPTSP2,,tTo)
exten => _x.,3,Hangup
log showing the below error:
[Mar 20 18:19:03] == Using SIP RTP CoS mark 5
[Mar 20 18:19:03] -- Called SIP/01730027200@IPTSP1

but if i use manual dial, it works perfectly. what could be the issue ??
