Hi Team,
We have freshly installed the incredible PBX, however, on calling b/w exts, I am getting error "Retransmission timeout reached on transmission uG3yl-xfLfsJ5aSGwXajJQ.. for seqno 2 (Critical Response) -- See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions Packet timed out after 17793ms with no response ".
I also checked the logs after turning Sip debug on but I am not able understand why the re-transmission happening. I really need to fix this issue/
