Some numbers not working on betamax?

Got two new ipkall numbers in 253 and 425 area codes, and they give
the trace below.  Work fine using regular phone.

znork*CLI> core set verbose 3
Verbosity was 1 and is now 3
  == Using SIP RTP CoS mark 5
    -- Executing [94@internal:1] Dial("SIP/16-00000063", "SIP/outbound/14256063067") in new stack
  == Using SIP RTP CoS mark 5
    -- Called SIP/outbound/14256063067
    -- Got SIP response 500 "Internal server error" back from
    -- SIP/outbound-00000064 is circuit-busy
  == Everyone is busy/congested at this time (1:0/1/0)
    -- Executing [94@internal:2] Hangup("SIP/16-00000063", "") in new stack
  == Spawn extension (internal, 94, 2) exited non-zero on 'SIP/16-00000063'

Looks like a betamax problem.
Here's something reported from voipraider.com :
