[Freeswitch-users] Codec/RTP rate variable is null

[Steven Ayre]

It's probably because the call hasn't been answered yet, which means codec
negotiation hasn't completed yet. They have sent you their supported codecs
in the INVITE, FreeSWITCH is configured with which ones it supports but you
haven't yet decided which codec to actually use for the call and therefore
you haven't picked a rate yet.
