2 of our ISDN lines attached to a te410 card (only 2 in use on that card) both started to give 'reject frame errors' after an zaptel 1.4 update. prev. i was using a version about 2 month old - 'make update' updated it to rev '4301'. I contacted our telco and they say line is clean, not a single glitch within last 48 hours. When I get the: ERROR[2834]: chan_zap.c:8248 zt_pri_error: !! Got reject for frame 14, retransmitting frame 14 now, updating n_r! It is always when incoming call on ISDN hangs up. (calls going ISDN -> IAX). Anyone else seing this ?
