The capture below is from an inbound call to 3 phones within a ring group. A SIP
Invite
triggers
a call flow for each of the 2 phones that ring. One phone was set to "Do not Disturb", so no
Invite was sent from the VoIP provider and does not show here.
Note: If the Vertex is monitoring all phones in the ring group and one or more phones do not
display here, the Vertex is not seeing a SIP Invite to that phone. We have encountered
locations where some phones are communicating via unencrypted SIP, while other
phones in the same ring group are using alternative signaling. Further analysis would
verify whether this is the case and your VoIP provider would need to remedy.
This shows that extension 204-CID1 answered the phone call since the
OK
was sent by the
phone after ringing. Extension 205-CID1 received a
Cancel
from the VoIP server at the same
time the other extension answered.
