Can i use conference among internal extension number???\
As previously mentioned you can reduce the number of timeslots configured for the E1 in order to free a DSP to provide at least one conferencing session based on G.711 using optimised resources. You would need to significantly reduce them in order to acheive this, to at least 16 and will provide a single conference session. The question is can you afford to do this? You state that you have four IP Phones connected, so a full 30 Channels seem a little excessive for only four phones?
The simplest solution would be to purchase an additional PVDM2, the Cisco 2821 has three PVDM slots, the question is how many sessions you require? as this will determine the size of the PVDM? In order to provide 30 Channels and at least one 1 conference session you will need at least a PVDM2-16.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
