[Freeswitch-users] Extract variables from 300 redirect

[Joseph Waite]

Hi Guys

I am wondering if its possible to extract a custom variable from a 300 Redirect response from a billing system?

Effectively I am trying to add a custom variable to the 300 message to give a maximum call length to then use in the dial plan for a Scheduled Hangup.

Any pointers of how to do this or the magic words to search confluence/google with?

Regards
