Hello,
We are using an application that use sendData for a while and we have now an issue on a customer site for some IP Phones, with CUCM 8.6.2. Some time sendData fails but the error message is null. Some time it works but it takes 3 second to send data as normaly it takes 300ms.
There is no problem to create the terminal and add phone and a call observer, we have no evidence the phone is Out of Service.
We are trying to get CUCM CTI logs but it does not seem to be easy to get them from the customer.
Does anybody has encountered random errors with sendData ? What was the cause ?
Thanks and regards,
jmlacoste

There have been reports of sendData() acting slowly, and we are actively
investigating them. Currently there is no reason in JTAPI for any issue, and
the sendData() code hasn¹t been changed at all recently.
Regarding the failures where ³error message is null², could you elaborate?
What method are you invoking on the PlatformException that returns null? Are
you checking the .getErrorCode() and .getErrorDescription() methods?

Actually, we use Exception.getMessage() which returns null in this case.
By the way, the issue is on CUCM 8.6.2 on which we have little experience
On the mokup the two 7962 are working well although the two 7942 get random errors ???

I have problems with sendData(), if I often send more then one times every 750ms. Sometimes the Phone revice a few seconds no data.
Try to call sendData() 100 times in series. Did you get the same errors?

There is a known limitation of some phone models when handling rapid/simultaneous XSI requests via CTI. The workaround - as you hint at - is to add some delay to avoid simultaneous requests.

You can also send a HTTP Request to the Phone. It is more stable.
