Current setup:
- CUCM: 11.5
- IM & Presence: 11.5
- Expressway-E: X12.5.4 (Single interface box behind NAT firewall on DMZ)
- Applied Licenses: Traversal Server (LIC-EXP-E) and Expressway Series (LIC-EXP-SERIES)
- Expressway-C: X12.5.4
- Applied Licenses: Expressway Series (LIC-EXP-SERIES) and H323-SIP Interworking Gateway (LIC-EXP-GW)
My expressways are configure for MRA. I am able to connect from outside of the network with Jabber on iPhone, iPad, and a laptop. Everything registers as it should with CUCM, CUC, and CUP. I am able to chat and check voicemail with no issues.
When I try to call another device (on the internal network) that is registered with CUCM, I receive the following error on the Expressway-C, "Call license limit reached: A call failed because there were no available traversal call licenses. You are licensed for concurrent traversal calls." From what I understand, devices registered on the same CUCM are considered "Registered" calls and not "Traversal" calls. Given that, it seems that I shouldn't need traversal licenses.
Any ideas or suggestions?
