Hi All, I had a successful chan_SS7 working with A@H 2.5, happily calling with Sangoma A101. But after I upgraded to Trixbox I got the following error (keeping the same configs) : Short MTP2 frame len 1 < 5 on link 'l1'. Jun 14 13:04:13 DEBUG[5472] mtp.c: Last raw bits on link 'l1': f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 f9 fb ef be c0 60 1e 95 bf 3f 7d f7 d8 0c 03 d2 b7 e1 e7 ef be fb Jun 14 13:04:13 NOTICE[5472] mtp.c: Short MTP2 frame len 1 < 5 on link 'l1'.
