Using A2A WSDLS
The WSDLS for A2A for PY2012 (ATS and Production) will remain the same as the ones you are using for PY2011. No changes or upgrades to WSDLS are required on your part if you are already using A2A. This is true for ATS and Production.
Also, because there are no changes to the WSDLS, you should only use the la.www4.irs.gov URL for all A2A services in ATS and Production unless instructed otherwise.
Note: You should not use the la.alt.www4.irs.gov URL unless instructed to do so by IRS. If used other than when instructed to by IRS, you may experience delayed responses from MeF.
