I have an MIR (ASC) server where MBG SRC recording already works. I am trying Active Device Recording and have followed the ASC documentation for CSTA3 with MX-ONE for this. On the phones, I've set the recorder address using the config file as per the doc. I can see the call info in MIR's PowerplayWeb, but the audio stream is missing. If my understanding is correct, the recorder will send SIP messages to instruct the phones to send it a duplicate RTP stream during a call.
In traces from both recorder side and phone side, there doesn't seem to be any communication between them.
Does anyone have experience with this type of recording with MIR or even the old MCR where the phone sends the duplicate to the recording server directly? I am just looking for ideas on what else to check and look at. Thanks.
