I configured tie lines between MD110 (BC 12.6) and Alcatel 4400 (release 5), maybe I can send You settings from my MD110, but I can't send them now, because I'm on holiday. There was trouble with Alcatel, because it has own propietary Qsig protocol (I think it's ABC F or something). There was trouble with Alcatel's operator, if operator diverted the call, B party didn't see A party number, and there was no other diversion posibility.So if You want, I can send You settings next week. But only from MD110, Alcatel 4400 was configured by another guy, maybe I'll ask him for these settings.
