Howto monitor a CTI link

I’m looking for a solution to monitore a CTI link between Asterisk and CTI client appalication; so that as soon as the link is dead of freezed, i can receive a mail. I’m actually checking Zabbix and Nagios, but i’m not quite sure that they will help.
Thanks if you have any idea.

Please try again on the right forum. Probably Asterisk Support.
