Hello,
I am using SPA504Gs with FreePBX and when I forward calls to a DID associated with an extension (i.e. 1003) the transferred calls fail because the SPA504G is including a SIP Diversion header in the Contact field that is unrecognized by our SIP Trunk Provider. Is there any way to prevent the Diversion header from being included in the call forwarded message?
Thank you.
Chris
