SipThreadCreationError

The telephony engine attempted to create an internal thread object. The thread creation failed. Make sure your system has enough free resources (memory) to perform the operations you are requesting from the telephony engine.

Thread creation errors are generally associated with the application process space consuming too much system memory. To resolve this error, you may want to consider disabling certain features of the media engine such as conference calling. You can also reduce memory requirements if you reduce the maximum signal length of internal media engine signal paths by specifying a smaller number for the MaxMixerLinebuffers member of the START_SIP_TELEPHONY_PARAMS structure that is passed to the StartSipTelephony and ReStartSipTelephony API procedures. Reducing the default stack size for threads in your application may also allow your process space to consume less system memory.
