other persons participate in the call.
You can initiate a conference by calling the first person, and then put the first person on hold to call the second
person. You can also include another person when you in the middle of speech with a person.
Conference can be made between PSTN and SIP calls or between two SIP calls. The parties to a conference can
be:
