If you need to set the Timeout on a Profile in url_response, please consider doing it using either the Raw Configure (in IM or Admin Console) or the Admin Console > Configure. Avoid the IM GUI because it only accepts a 2 digits value. So, a Timeout that contains more than 2 digits (configured in Raw Configure or Admin Console) will only show the first 2 ones (i.e. a Timeout set to 120 sec's will appear in IM GUI as 12).
I hope it helps.
