I have a TE410P in a Dell 2650 running in production on an older redhat distribution. The various packages have gotten old and I can no longer been able to build asterisk on this machine. I have prepaired another 2650 running SUSE Enterprise 10.1 sp2 (my workplace standard) to replace it with. When I swap in the card in my new machine Asterisk starts without error, however the spans remain in red alarm and will pass no calls. Ztcfg indicates the correct signalling... being found for the zap channels. On the SUSE box with the wct4xxp module loaded (and the card NOT installed) loads the following: lsmod wct4xxp 411904 0 firmware_class 25984 1 wct4xxp zaptel 203140 1 wct4xxp crc_ccitt 18432 1 zaptel I am suspecting that echo cancelling firmware is being loaded (I don't have an echo cancellation module installed on the TE410P) and I'm not sure if any firmware should be loaded for the te410p ? or how to tell if it is or if I can prevent it from being loaded. Lsmod on the working redhat box is simply, wct4xxp 89472 96 zaptel 184224 240 [wct4xxp] I have also attempted to do a make distclean and make menuselect with & without [*] 1. FIRMWARE-OCT6114-064 [*] 2. FIRMWARE-OCT6114-128 ...but perhaps part is not being cleaned out. Or is this firmware required for this card (and not the echo cancellation) with the current module? Thanks, John
