Currently running v15 (SP1) and Polycom IP550 phones. When "record all calls" is enabled on any extension, outgoing DTMF signals from that extension are not received by remote auto attendants. As soon as recording is turned off, DTMF tones are received normally. I have experimented with PBX Delivers audio, and different codec combinations for both the extension and SIP truck with no success. Any suggested solutions would be greatly appreciated.
