Symptom
This enhancement request is to have more logging for SIP phones (like for SCCP phones) in SRST mode, so it can be confirmed from the logs if the SIP phone is registered or de-registered
Example from SCCP phone
006086: Nov 25 12:08:25.969: %IPPHONE-6-REGISTER_NEW: ephone-1:SEP1CE6C799721B IP:185.47.240.8 Socket:1 DeviceType:Phone has registered.
006092: Nov 25 12:11:30.493: %IPPHONE-6-UNREGISTER_NORMAL: ephone-1:SEP1CE6C799721B IP:185.47.240.8 Socket:1 DeviceType:Phone has unregistered normally.
CUBE has only one syslog message for the very first SIP phone to "activate" the pool and one syslog message for the last SIP phone unregistering and "deactivating" the pool, not for all phones
Example:
006064: Nov 25 12:00:03.338: VOICE REGISTER POOL-1 has registered. Name: IP:185.47.240.17 DeviceType:Phone-
006065: Nov 25 12:00:03.338: %SIPPHONE-6-REGISTER: VOICE REGISTER POOL-1 has registered. Name: IP:185.47.240.17 DeviceType:Phone-
006076: Nov 25 12:04:15.595: VOICE REGISTER POOL-1 has unregistered. Name: IP:185.47.240.14 DeviceType:Phone-
