Getdigits not detecting the pressed digits randomly?

[cobyvg]

It looks like the get digits method is sometimes working and sometimes no. We have been testing deeply this because we are 99% sure it is something in our side but we have reduce the test to simply send the same XML to plivo several times and sometimes it is working and sometimes the digits are ignored.

Do you know that could be the reason? We are thinking about the server's communication issue or something like that. In the Plivo dashboard the xml that is received is identical for both cases: working properly (detecting the pressed digit) and ignoring the digits completely (so it reaches the timeout and finishes).

We will really appreciate your help. Thank you
