Hi Daniel, Thanks for the quick response. So if I do not use Netstrings, does Kamailio allow me to create a custom logic in the script. For eg. if I decide to use newline as a delimiter, can I keep buffering the message until I encounter the delimiter from the event route and then execute whatever I have to within the script??
