I have a CME 4.0 box and about 10 IP phones. When I make a call out to the PSTN over an FXO port my Conference Softkey disappears. Is this just a restriction of FXO or is there a workaround?
How do you have your dsp resources setup on your router? The situation can vary depending on the type and number of dsps. If you only have one dsp chip, which would be a pvdm2-8 I believe, you're stuck with either conferencing or voice port termination. A single chip can not do both. If you have a pvdm module with more than one chip on it, a second chip can be assigned to do the conferencing if it is not already in use.
Hope this helps,
