Hi, I'm testing asterisk 1.8 and recently added q931 subaddressing. If I use dialplan function CALLERID(dnid-subaddr), it will not send Sub-address into PRI. But when I use Dial(dahdi/g1/number:subaddress), it works. CALLERDID(subaddr) works as expected. I've looked into sources but I'm not able to trace it. Any idea? MV
