Description:This message appears with 2 different brands of router, NETGEAR RT328 and Allied Telesyn AR130. These same routers, when connected to a Jtec Switch QBRM card correctly establish a call, without any configuration changes to either router.

When attempting to use B410P in NT mode, as soon as inbound digital call is attempted, console show this error (with pri intese debug span 3).

This setup was to check out the issues with ASTERISK-14895.

I have a ZyXEL Prestige 128 that I can also setup, reckon B410P is going to give same error.

Configuration issue! It's documented now for all to see...

console output:

This is with 2 NETGEAR RT328's.

This closes this bug. Sorry for the noise.
