  <br />

* The issue persists after the user follows the instructions in [sk35563](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk35563) to set the maximal number of participants that can take part in a conference call to "50".

## Cause

There are two possible reasons for this problem:

1. An incorrect 'Protocol Type' is selected in the SIP service.  

2. The SIP max re-invites table becomes full after a while, which results in VoIP (SIP) calls to drop.
