I've have configured VOIP provider and voip device.
Sip config as follows
sip.conf [operator] canreinvite=no context=from-operator host=operator_ip secret=operator_secret type=peer qualify=yes port=5060 defaultuser=operator_number fromuser=operator_number fromhost=operator_ip fromdomain=operator_ip dtmfmode=rfc2833 authuser=operator_number@operator_ip trustrpid=yes sendrpid=yes insecure=invite [office1] type=friend secret=my_secret host=dynamic qualify=yes directmedia=no context=from-office nat=force_rport,comedia extensions.conf [from-operator] ; call office1 exten => _X.,1,Dial(SIP/office1) exten => _X.,n,Hangup() When I call my operator number, it should redirect to office1.
However I'm getting following error.
Call from 'OPERATOR_NUMBER' (X.55.178.68:5060) to extension 's' rejected because extension not found in context 'from-operator'. I don't know where that 's' is coming from?

s is "empty extension" or "start extension", see here
That mean asterisk not able determine DST on incoming call. Usually, that is call to sip:ip_here:5060
S will not match _X. pattern(which is DIGIT+something, at least two positions).
You can catch s in dialplan(write rule for s) or you can try find DST from sip headers(see sip debug to determine if that possible).
