Hi all,
We've tested direct-push to our exchange servers from a number or JasJars.
When we use Vodafone UK or T-Mobile UK, all is well, the device adjusts the ping frequence and ends up at around 30 minutes for both providers and all is well....
However with Orange, it stays at 480 seconds (the lowest default), after the timeout the device always logs PING FAILED.
We've noticed that Orange uses 3 different gateways on their GPRS network, when a connection is idle for approx 2 minutes it changes randomly to another gateway, when the Exchange box tries to send the packet back using the http(s)-keep alive the connection between the gateway and the device is lost, hence, the keep alive won't be returned, effectively rendering push-mail useless on orange.
They have confirmed to us that they do this to load balance their gateways and seem to have no plan to rectify this.
It's ironic since they advertise the new C600 rom on their homepage stating: "Get push mail now!" when it will only work for the first 2 minutes of each ping cycle.
Anyone else noticed this problem?
Cheers,
Tobey
