Sorry, for the following long paragraphs, but, really it is a very strange scenario.
Issue concernig the conference and Music on hold.
When an IP phone inside my company intiate a conference even with also inside other IP phones or outside calls, and this intiator IP phone make hold; all rest conference participants hear each other carefully without any interupption.
Problem comes up when an outside caller intiate a conference with an IP phone inside my company and others outside my company, this inside IP phone make hold; all rest conference participants will hear Music on hold and can't complete the conference.
So, if you please, if there is a solution for this issue. If not, how to global disable the MOH at all.
Note: My CCM is 4.2(3).
