David Staudt | Within CDN there is support for application developers building SIP trunk clients and SIP line-side devices as clients of Cisco call-control (UCM/CME), but AFAIK there are no programs which support using Cisco sip devices as clients of 3rd party call-control. That being said, the SPA5xx phones are not handled under the CDN umbrella, so it's possible that the respective Cisco business unit may have different policy. I would suggest contacting the SPA5xx product management team, via your Cisco account rep. |
