Hi Gents,
Currently im having issues to register Algo 8081G SIP Audio Alerter to Cisco CME 10.5
Seems like at Algo GUI, both extension (810) & (811) already successfully registered in the CME. However when I tried to do the test call from other ext to both Algo number, it just replied with dead tones.
I've share the snippet of the config as follow and debug log
