Hello list, I have a A104d sangoma card and I am trying to install chan_ss7 1.3 with asterisk 1.6.0.6, wanpipe-3.4.6, dahdi-linux-2.1.0.4. Following the guide from Daniel Pizarro (http://www.asterisk-peru.com/files/procedimiento_sangoma.txt ), the compilation works fine, the link goes green and asterisk starts correctly. But I can't get the ss7 link alignement with my provider; I have the following messages in my logs instead: [2010-02-07 18:10:08.280] NOTICE[19620] mtp.c: Excessive poll delay 7463! [2010-02-07 18:10:10.992] DEBUG[19620] mtp.c: Suppressed 2726 bad frame debug log messages on link 'l1' [2010-02-07 18:10:10.992] DEBUG[19620] mtp.c: MTP2 bitstream frame format error, entering octet counting mode on link 'l1'.
