I've a call center using IAX softphones provided by a third party.
We've observed problems where the IAX phones seem unable to use our PRI
trunks. A sample anonymized call is provided below with the PRI debug
calls embedded. Any thoughts,
comments or suggestions would be welcome. In anonymizing it, I preseved
the format
and number of digits sent.
