[Leo Salcie Tejeda]

Hi,

I'm playing with a Cisco 1751 IOS IPVOICE. Right now as a gateway is working with one FXO and FXS Card, but can't find if can support register a softphone. Does Cisco 1751V support SIP registratration?.

Thanks in advance.

Cisco 1751V support natively only old SCCP phone. You need to  upgrade NVRAM to at least be able to support CIPC on CME 3.1. Additionally, Router IOS is not available from Cisco.com.
