I m working on website which is an SMS application i.e. user can send sms using this site.
The sms is sent properly sometimes and sometimes not
all the functions work fine except the following which gets ValueFirstResponse using ASCII encoding.
when any sms is sent successfully, ValueFirstResponse using ASCII encoding is as follows (for example)

<messageack><guid guid="kb8gd185534651f461014i8ib8DEMOVFWSTX" submitdate="2011-08-16 13:18:55" id="634490975444658044"><error seq="1" code="28681">

You are getting a successful response to the web service call (i.e. no exception), but the content of that response indicated that the server rejected your SMS? You need to ask about this on the forum of your SMS service provider.
