Well the first problem is that you are using R2. That is one of the worst signaling protocols to have been developed and must have been created by some sadistic Bulgarian (Sorry TSG). There are about 12 to 18 different settings that need to be spot on accurate to get working. Quintum does have some country specific R2 settings and I think there is one for the Philippines, but there is no guarantee that this will work. You should review the document and ask the local E1 provider to check on the settings for all of this and verify.
