Log:
overlap receiving: automatically send CALL PROCEEDING when dialplan starts

Following Q.931 5.2.4
When the user has determined that sufficient call information has been received the 
user shall stop T302 and send CALL PROCEEDING to the network.

Previously timeouts were possible if the dialplan took a long time to issue any
response back to the network.

Verified that our local TELCO also does the same.

(issue #16789)
