Can anyone assist in making this call work? Have been frustrated for the past one week and would really like to see it work.

One of:

astHP doesn’t exist in sip.conf;
astHP has a dynamic address but there is no current registration for it;
astHP has qualify enabled and is failing to respond (even negatively) to Asterisk’s OPTION packets used to probe the connectivity.

sip show peers, users and registry may reveal more.
