Hello all, We had an experimental system which works on OpenLine4 telephony card and Asterisk 1.0.9. Customer asked to upgrade Asterisk to 1.4, then we found our problem: At first Asterisk 1.4 does not compile chan_vpb.so. The problem is it tries to compile chan_vpb.cpp to chan_vpb.o and chan_vpb.oo, then try to link them together. I manually compiled it, then make went smoothly. But it refused to load chan_vpb.so I switched back to Asterisk 1.2, it segfaults on chan_vpb.so. my VPB driver details: vpb: Driver Version = 4.0 vpb: major = 254 vpb: tmp [0xf0342000] dev->res3 [0xf0342000] vpb: tmp [0xf0300000] dev->res2 [0xf0300000] vpb: 0WS Write cycle vpb: Manufactured 17/03/2004 vpb: Card version 20.03 vpb: Serial number 41201496 vpb: Setting up udev... vpb:1 V4PCI's detected on PCI bus I actually installed a newer vpb driver (4.0), it did not work. I installed 3.1, and tested to be working.
