Configuring 877w and 7940 with SIP firmware for VOIP
I thought a Cisco 7940 with SIP firmware can work with a SIP VOIP provider?
Yes and no. Depends on your VoIP Servce Provider (VSP).
Some VSP, like mine, will only allow one session at any time. This means if I have two or more handsets, like mine, only one handset will be able to authenticate with the VSP. The other handset will be able to authenticate but will be unable to receive any incoming call.
Now back to your issue, check with your VSP for their settings. Run a debug from the phone and find out what is going on. One easy option is to install a software-based "phone" and get that to authenticate with your VSP. Once you iron out the configuration issue with your sofware-based "phone" and your VSP, you can easily "export" the config to your hardware. Does this make any sense to you?
