Mid-Call Reinvite repsonse

1. Brekeke Product Name and Version: SIP Server 3.3.8.1

2. Java version: 8

3. OS type and the version: Server 2008 R2

4. UA (phone), gateway or other hardware/software involved:

Rauland R5 to Cisco CM

5. Your problem:

A call is established from Brekeke to Cisco CM. During the call, Cisco redirects the call to a dispatcher's extension. Cisco then sends an Invite mid-call to Brekeke. There is no response from Brekeke so the call is terminated from Cisco. Can Brekeke send a mid call 200 OK response?

R5 does not support re-INVITE.
It is the reason.

Let you disable re-INVITE at Cisco.

I understand that R5 does not support the re-INVITE. That is hwy I was wondering if Brekeke can intercept that re-INVITE and send an acknowledgment on behalf of the R5 device. Is that possible?

Also, Cisco cannot disable the re-INVITE for some reason.

Let you add the following line in the Deploy Patterns . It blocks re-INVITE and respond by SIP server.
