Since that time, we started to notice some failed inbound calls. These calls terminate with an ISDN cause code 47 'resource unavailble'. Most of the time I see this error on the first or second channel on the second span in a trunk group (This is the providers trunk group for hunting, not an Asterisk trunk group). All the PRIs are setup as individual spans, we are not using NFAS. If the provider sets the hunt method to 'least recently used channel', then I can receive calls on other channels on the secondary span, it is just the first 2 that consistently fail.</div>
<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">We have had occasion where the error occurs on first span. If enough calls come in at the same time, callers who happen to land on channel 3 or above are OK. When the problem happens on the first span, if we physically disconnect the first span(RED alarm), the calls hunt to the second span and all calls seem to process properly. The only way to clear the cause 47 errors from the first span is a power cycle on the provider equipment. Power cycling my equipment does not solve the problem, only when I cycle their equipment.</div>
