SV8100 Standard SIP port is 5070. See MB84-20-01 to confirm what port your system is set to look for Standard (non-NEC) SIP phone registration on. 5070 is default.
Here is an example of a Polycom IP5000 setup to login to an SV8100. We are using username/password using Personal Index for IP Extensions.
See attached photo for example. I have not included shots of the dialplan, but this site is 4-digit dial-plan with dial 8 for trunk access.
If you need help with the dial plan, let me know and I can assist.
