i setup a asterisk relay system.the structure is Gw(s) -->asterisk(a) —>asterisk(b)---->gw(d).all is sip protocol.
all works well.but the active calls on asterisk is less than 125,that mean sip channels can not over 250. when call over 125,warnnings appears. as following.is someone have good ideas? thanks
