[OpenSER-Users] crash when checking empty destination uri

Hello, I have the following line in my script which causes OpenSER (1.2) to crash when the execution gets there for an ACK. if ($du=~"[@:](192\.168\.|10\.|172\.(1[6-9]|2[0-9]|3[0-1])\.)") It gets at this line when an ACK is received and after loose_route() returns true. So I am guessing the destination uri is null at that point and the check causes OpenSER to crash. If I add the following check then everything works fine. if (isdsturiset() && $du=~"[@:](192\.168\.|10\.|172\.(1[6-9]|2[0-9]|3[0-1])\.)") thank you George Disclaimer The information in this e-mail and any attachments is confidential.
