Hi,
I am trying to implement a Ring Group with
a Memory Hunt ring strategy.
The scenario looks as follows:
There is a subscriber A, B and C. All of them are members of the same
Ring Group.
When there is a INVITE to a "Ring Group" Opensips should send an
INVITE to subscriber A, after 10 seconds it should send an INVITE to
subscriber B and after another 10 seconds one more INVITE
to subscriber C. If there is no 200 OK from A,B or C in 40 seconds,
call should be forwarded to Voicemail server.
This should look something like:
Caller Opensips A B C
----------- INVITE ---------------> | | | |
| | | |
<---------------Trying ------------- | | | |
| | | |
| --- INVITE -->| | |
| wait 10 seconds | |
| ------- INVITE ----->| |
| wait 10 seconds | |
| ---------- INVITE ----------->|
| wait 20 seconds | |
| ------- INVITE ------> Voicemail
( 180 Ringin and other replies omitted).
Is the above possible with Opensips? Which functions should I use?
I understand forking is done with append_brach(), but how to make
Opensips to wait (10 seconds), before sending an INVITE to next
destination?
Any help, suggestions very much appreciated.
Best regards,
Chris
