[Freeswitch-users] Stupid question ;-)

I have some var: <action application="set" data="input_fail_counter=0"/> And in some moment I want to increase it by 1. I try this way: <action application="set" data="input_fail_counter=${input_fail_counter}+1"/> And have result input_fail_counter=0+1 i.e. just string merge... How to handle it right way in dialplan? -- С уважением, Равальдини Патрик Стефанович Инженер по тестированию ООО «Центр речевых технологий» Тел.: (812) 325-8848, доб. 6736 Факс: (812) 327-9297 E-mail: patrick@speechpro.com http://www.speechpro.ru
