I configured a ring group (let's say 100 - Terminal Cascade Ring with Cascade Ring Timer e.g 5 seconds) and put few members in it:
101 ... SIP phone
102 ... SIP phone
103 ... Mitel phone
When I call the ring group (e.g. from 200) 101 rings, after 5 seconds 102 rings and after another 5 seconds 103 rings, however when I drop the call and look at the call history of each of the phone sI can see following:
101 shows missed call from the ring group pilot number - 100
102 shows missed call from the ring group pilot number - 100
102 shows missed call from the caller number - 200
Is it a bug? Or is there any way to fix it in the configuration?
The SIP INVITE command has extension 100 in From, Contact and P-Asserted-Identity (200 si not there) headers.
