I am experimenting with using SIP lines on a Partner using a Cisco SPA8000. The call quality is excellent, but I can't get the device to receive incoming calls. It's not the ACS, its the Cisco device because it happens with an analog handset as well. I have a ticket opened with Intermedia (they recommended this particular device but don't work on it that often) but was wondering if anyone had any experience with this.If it works it really expands the white label market for SIP so I'd really like it to work :) thank you in advance.
