Options for SIP Providers missing in V20

[telis]

In the v18 when configuring a SIP trunk the following options are available.

Supports Re-Invite
Support Replaces

I have no insight in to what they do but I usually have to untick them to get call transfer to external numbers to work in CFD.

I can't find them in V20. Do they still exist?

 

[telis]

My CFD scenario started working for reasons I don't understand so this is no longer important to me..

There are options that have been hidden/removed/are in progress. I believe you can export and import the trunk to set some of them.

Those options are not available in V20.
The only option is to export your Sip Trunk, make the necessary adjustments and import.
