[Freeswitch-users] Detecting Errors when dialing through multiple gateways

[Sean Devoy]

Awww, but there is a trade-off here.  In my bridge, the "back up" expensive
gateway starts connecting after only 8 seconds.  Using your schema, in some
cases, the first or "cheap" gateway takes the full timeout limit to expire.
Only then, after 25 or 30 seconds, does the backup start trying to connect.
Too many users give up after 20 or 25 seconds of silence.  Few will wait for
a 25 second timeout, followed by a 12 to 15 second connection.

 

But, if error detection is not possible in the sequential dial way, I like
your approach, but with an extra "play" message saying "ooops, rerouting,
hang on, hang on I can do this"

Hi All,

 

I have been having pretty good luck with redundancy by dialing through
multiple gateways like:

<action application="bridge" data="sofia/gateway/cheap/1xxxxxxxxxx,
[leg_delay_start=8]sofia/gateway/expensive/1xxxxxxxxxx"/>

I'm curious why your're doing simultaneous dial instead of sequential dial
here. In any case, you can have multiple bridge apps instead of doing the
comma-sep list:

<action application="set" data="continue_on_fail=true"/>

<action application="set" data="hangup_after_bridge=true"/>

<action application="bridge" data="sofia/gateway/cheap/$1"/>

<action application="log" data="WARNING Bridge attempt failed
${bridge_hangup_cause}"/>

<action application="system" data="/usr/sbin/send_notification_email.sh"/>
<action application="bridge" data="sofia/gateway/expensive/$1"/>

Try it out. Also, don't forget the standard disclaimer

If gateway cheap fails, the call goes through on the expensive gateway.
That is fine, but I would like an email notification of the failure on the
cheap gateway.  Is there any way to do that?  The support group at the
gateway vender is very good at correcting the problem when notified.  I
would love to send them an email of failures automatically.

 

Thanks,

Sean
