In case of TCP transportation type, the timers will still pop as usual. In the event of timeout, however, the stack will not retransmit; it will instead rely on TCP itself to do the retry. Table 17: Message Retry Counts, on page 25 provides the configuration data for the SIP retries that Unified Communications Manager maintains.
