We are currently experiencing an issue where calls from or to a shoretel mobility client will be dropped after 2 minutes and 30 seconds. We've run packet captures and taken logs from the shortel equipment, thus far things seem to be pointing in the direction of the Aruba wireless we have.
The reason the call is dropping is because the SIP update messages being sent by the mobility client are not making it to the mobility router, thus after so many attempts at sending it, Goodbye messages will be exchanged and the call will be dropped.
I have run some packet captures both on the aruba controller itself and off of our switch the controller is attached to....reviewing traces taken directly from the controller were not useful as the traffic is tunneled and all I see are 802.11 frames, no actual endpoint traffic. The traces taken from the switch were much more helpful, as I can see the mobility client send the first SIP update but after that no further updates come in, even though the clients logs say otherwise.
I think we are at a point where we will be engaging Aruba TAC and providing them with the traces and logs we've taken thus far.
Anyone heard of this?
