[Freeswitch-users] Conference Use-Case Question

Hi, I'm quite new to mod_conference and I've had good success implementing Stanislav Sinyagin's conferencing solution <https://txlab.wordpress.com/2012/09/17/setting-up-a-conference-bridge-with-freeswitch/> on his blog for our freeswitch setup. This is fantastic for planned conference calls where everyone can dial into the conference line. I'm now looking to address the use case where 1 person is talking to another and suddenly needs to pull in one or two more people into the call to discuss (sort of a dynamic conferencing solution). Is this possible and what's the best way to go about achieving it? Appreciate any advice you can give me. Thanks Cody
