Gonna need the verbose output from the Asterisk CLI as well. Add 'verbose'
to the messages section of logger.conf and do a 'logger reload'.

Can you also break each of those spans out to individual groups and
retest? Does it just happen once you hit a specific span, or perhaps a
certain channel?

Have you contacted your PRI provider to test the lines and watch the
signalling and such go across the connection?

Also, can you please attach the output of 'pri set debug span 1' and
change the '1' to whatever span is failing to place the calls? You can
attach a separate file for each span if you wish.

# asterisk -cvvvn | tee /tmp/console_output.txt
