This means that the config file you used contains a line that osmo-nitb does not understand.
Looking in the git logs, I could actually not find this config item anywhere in the past of our main line osmo-nitb. So maybe this config file once worked with a development branch of osmo-nitb. Sounds related to telephone numbers.
I'd suggest simply removing the extension-prefix line from openbsc.conf.
Also note that we've moved to redmine, and the page you referenced was migrated to http://osmocom.org/projects/cellular-infrastructure/wiki/Ettus_USRP_B2xx_fam... (which doesn't mean that anyone fixed it, though)
Hope to have helped,
