Confirmed live: Dial() actually placed the call to "PJSIP/pstn_check_busy@
pstn-trunk" instead of the dialed number. Root cause is systemic, not one
line — Goto(label,1) to a *different named extension* (as opposed to a
same-extension priority label, which _pstn_ring_member_block already knew
to avoid) resets ${EXTEN} to that label's own name. Every helper extension
downstream of a Goto (pstn_check_allow_out, pstn_check_busy,
pstn_intl_check_country, pstn_intl_country_denied, pstn_personal_inbound)
was reading ${EXTEN} expecting the originally-dialed number and getting
its own extension name instead.
This wasn't just cosmetic: pstn_check_allow_out's REGEX approved-number
check compared against the label name too, meaning restricted-tier
extensions could never successfully place a call regardless of whether
the number was actually approved.
Fixed by capturing the real dialed number into PSTN_DIALED (outbound) /
PSTN_DID_CALLED (inbound) at each entry point, before any Goto, and using
that instead of ${EXTEN} in every downstream extension.
