As a supplement to the above:

Kamailio is launched with -m 64 -M 4.

After researching, I've doubled the values and we'll see shortly.

Hi David,

Thanks for your reply.

After increasing the verbosity of the debugging, I found the following entries. So am I understanding the log correctly: the websocket module is trying to get some free memory (from Kamilio's general pool?). It doesn't receive any yet proceeds with parsing the response (I get this same parsing error even when it's working) and ultimately, it doesn't register the websocket?

I appreciate your (or anyone's) thoughts.

Regards, Tom
