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
..
The text message is sent and the call is connected, but Asterisk keeps
resending OK for the INVITE, and eventually drops the call after Transmission
timeout.
If I insert a WAIT after SendText, the order of the OKs changes, and everything
works:
same => n,SendText(hi)
same => n,Wait(1)
same => n,SLAStation(line1234)
Here is the SIP message flow with WAIT (4 and 5 above are swapped):
1 phone => Asterisk INVITE
2 Asterisk => phone Trying
3 Asterisk => phone MESSAGE
4 phone => Asterisk OK (for the MESSAGE at 3)
5 Asterisk => phone OK (for the INVITE at 1)
Is there anything else I can do other than using WAIT (which might not be a
consistent solution anyway)?
Thanks,
Matt
