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

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"/> 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
