Hi Guys
This one is a mystery, I have my suspicions but really need Cisco BU to confirm the scenario.
SYMPTOMS
iPad <> iPad Works for Voice & Video when neither is registered to any CUCM
iPad <> J4W (LAN) Fails for Video as we would expect
CONNECTIVITY
Office Internet (non-CORPORATE LAN, Internet only WLAN)
No route to LAN (including no route to Tesco CUCM)
CUCM 8.6.2
Hybrid Cloud Solution (IM&P,WebEx)
J4W Client 9.0.2
iPAD CONFIG
IM&P: Logged into Cloud for IM&P as we would expect
IPT/TP: Since no route to Tesco CUCM the CUCM set up does not complete on the iPad client
TESTING
We have managed to get a capture from a Wireless Sniffer during the scenario.
- •- Capture Start (Wireless capture from point of User A’s iPad)
- •- Login to Jabber for iPad (User A)
- •- IM to User B
- •- Call to User B
- •- Call sets up for Video and Audio fine
- •- Drop call
- •- Log out of Jabber for iPad
THEORY’s ??
1. Maybe the iPads are some how using the SIP messages/sessions for IM&P and the client initiated Voice/Video call is falling into that session. Since the iPads are on the same network the Media stream can pass point to point OK?
2. Could the WebEx cloud be providing the CUCM type function to redirect the iPad SIP invite to each of the iPads who then call each other p2p? The capture certainly highlights a number of different WebEx IP addressing in the communication throughout the capture, even though during most of the capture there was only the Video call taking place on each iPad
From Reverse Lookup:
209.197.193.92 & 66.163.36.80 >> WebEx
50.16.240.125 >> Streamlined Login Experience - Streamlex
Any advice on why this works would be great.
