Hi all.
I have a SIP trunk which when users activate call forwarding to external destinations, callers get a “sorry your number cannot be routed at the moment,” message from the provider.
The provider claims that Mitel is missing diversion header in the invite for those calls. Where do you advise I should make changes?
Thank you.
