We are using PBX system 5.2.5 in our company.
There is too many incoming calls at same time, our managers are busy talking and we would like to use our own IVR message like 'please,wait for an answer or call later, the number you're calling is busy', when 2nd call incoming to an extension.
Any chance to setup this? Aswell manager should be able to reply on 2nd incoming call after finish 1st one or switching between calls. Thanks for advice
