Hello,
I am trying to make a design like below to work.
X-Lite ----- OpenSER ----- Asterisk ----->(PSTN Calls)
X-Lite registers with OpenSer and PSTN calls are routed through Asterisk
from OpenSER. When a call is sent to Asterisk, Asterisk tries to
authenticate the user on X-Lite. I maintain same username and password
for both OpenSER and Asterisk.
Now when an INVITE from X-Lite hits OpenSER, it goes through the
following script and is asked for Proxy Authorization:
if (!proxy_authorize("","subscriber")) {
proxy_challenge("","0");
exit;
}
When I dial a PSTN number from X-Lite, X-Lite at some point, ends up
sending two Digests (one for OpenSER and one for Atserisk) in same
INVITE but gets stuck with Proxy Authorization failure (from OpenSER).
If I take off the above proxy_authorize section from OpenSER script,
everything works fine.
Can anyone suggest a solution to this.
Thanks in advance.
