Thanks for the hint and sorry I miss this example.
But unfortunately I have a infinite loop if I use directly the example...
I tried to redirect the call to 101 when 102 is used (100 is making the
call)
When I used a config file like that:
# rewrite current URI, which is always part of destination ser
rewriteuri("sip:102 at christophe.fr");
# append one more URI to the destination ser
append_branch("sip:101 at christophe.fr");
# redirect now
sl_send_reply("300", "Redirect");
exit;
=> Infinite loop !
Now if I use only:
# append one more URI to the destination ser
append_branch("sip:101 at christophe.fr");
# redirect now
sl_send_reply("300", "Redirect");
exit;
=> The call is redirected correctly but if 101 cancel the call if have a
"Call failed: 404 user not found" on the device 100. Is it normal ?
Another point: in the example on the end of each URI, there is ":9". Why ?
Example: append_branch("sip:redirect at siphub.net:9");
And finally: the function append_branch() doesn't seem to accept avp value
...
Thanks,
Christophe

If you got OpenSER sources, look into examples directory, you have a
redirect.cfg file. Online, you can browse it via:
