As a final followup for the archives since this is now working, the
correct way to handle outbound calls for this pstn service provider
(Cox Cable) was to use pridialplan=unknown (per the provider). With
this parameter, essentially any number of digits can be sent to
them (eg, 7 digit, 10 digit).
As a side note, they allow CallerID Num to be forward to them and they
accept it, but they do not accept any form of CallerID Name at all.
