302 Moved Temporarily header

#1

Trying to setup a HT814 ATA, but the VOIP Provider cannot handle 302 Moved Temporarily header for call forwarding and have requested in I can configure the ATA to not use it and just place another outbound call when call forwarding is activated on the ATA.
Can you please suggest how I might be able to set that up?

#2

are you sure the provider supports 302?
how did you try this?

#3

You can’t in short term.
Change provider or set this forward on their system.
