[asterisk-users] External callerid issues using Q931 against Toshiba Strata

Hi Guys,
I currently have an Asterisk 1.6.2.18 server running a patched (see
below) libpri 1.4.10.2 connected to a Toshiba Strata CTX670. All
external calls come in via the Strata and then are routed to the
Asterisk server over a single PRI link using Q931. This setup is
working and has been working for some time (with various earlier
versions of Asterisk) and with a patch (read hack) to libpri I've
managed to successfully pass through the numerical portion of the
callerid from the Strata.
I would like to upgrade to Asterisk 1.8 or 10 and use libpri 1.4.12
but am having difficulties picking up the callerid from the Strata and
due to significant changes in libpri my patch no longer applies.
Below is a pri intense debug capturing the Strata sending through the
callerid with libpri upgraded to 1.4.12 (running Dahdi 2.4.1). Libpri
obviously receives the callerid information, but I am unsure of how to
actually access it in Asterisk. I expect that if the callerid
information is properly acquired and recognized in libpri it would
simply be accessible in Asterisk in the 'CALLERID(all)' variable, but
it is always empty. Internal calls from an extension on the Strata to
an Asterisk extension show the callerid as expected.
Does anyone have any tips on how to get Asterisk to use the callerid
passed through by the Strata?
Thanks!
Justin
