I have Call Manager setup running with DID . I want to have conference facility for users who are making calls from PSTN world where they reach any DID number and join the Adhoc conference.
Is it possile to do ?
MeetingPlace is the product designed for this. You can achieve an extremely basic version of this using MeetMe conferences by using a translation pattern between a DID and a bridge number; however, an internal user must start the meeting first by going off hook, pressing MeetMe, and dialing the bridge number. Until an internal user does this, external users will get a busy signal.
Also, MeetMe provides no security (pass code) so anyone can join the meeting. There is also no join announcement by default. You can enable a join tone in service parameters but no name introduction.
The lack of security is usually a problem for customers. Some people have developed elaborate Unity or CCX IVR front-ends that impose an artificial password on the caller before transferring to the MeetMe bridge number.
