Hi,
I'm using SendText to send a text message when the user picks up a line
in a SLA setup (even though I'm not sure the problem is related to SLA).
I'm on Asterisk 10.2.1 (same in 1.8.9)
[from-office]
..
same => n,SendText(hi)
same => n,SLAStation(line1234)
..
Here is a simplified version of the SIP messages:
1 phone => Asterisk INVITE
2 Asterisk => phone Trying
3 Asterisk => phone MESSAGE
4 Asterisk => phone OK (for the INVITE at 1)
5 phone => Asterisk OK (for the MESSAGE at 3)
6 Asterisk => phone OK (for the INVITE at 1)*** RESEND of 4
7 Asterisk => phone OK (for the INVITE at 1)*** RESEND of 4
..
Did the phone send an ACK for message 4? If not, that explains why
Asterisk is retransmitting the '200 OK'. Posting a packet capture of
this problem occurring would probably provide the details necessary to
figure out what is going on.
