To-tag updated on private side, why?
I have a call going from an application server (private side) to an Acme 4500 (ver. 6.3.7) which sends the call out to one of our providers (public side), the first provider sends an error message so via SAG regression a secondary IP is tried. I will preface my question with the fact that dialog-transparency is set to disabled and my operation-mode is set to dialog in my sip-config.
The question is, with the Acme Packet setup to act like a true B2BUA why when the 183 comes in from the secondary IP would it update the To-tag on the private side when all the retries and errors are being handled on the public side?
