Hi everyone, I've configured ser to work with semstalkflite module of sems. This is how it works: A user calls up sip:READOUTTHISTEXT@ser and ser should be able to play back "READ OUT THIS TEXT" using a media server(sems). Now it seems to be working fine, but, after having a INVITE-200OK-ACK dialog b/w ser and caller "A", ser is not absorbing the ACK. i,e, for some reason, Caller "A" keeps sending ACK again and again. FYI.. caller "A" uses X-lite. Here is the part of the ser config file that i've modified: if (method=="ACK"){ log(1,"Pankaj --> I've hit ACK!! "); # absorb ACKs break; }; Isn't it good enuf to absorb the incoming ACKs? Anyone with any pointers??
