    I would like to know the link between trunk (from erlang B formula) and VoIP (i.e. Kb/s, …)
    thanks

    It will depend on which codecs you use and other factors. With CODEC G.729a, the bandwidth for each trunk is about 13.2Kbps (voice only) and 21Kbps (voice and fax). Sorry, I have notime to explain all our calculation here.
    Regards
