Hi,
Unfortunately this may be a use case which is not supported as of yet in HMP 3.0 SU baseline. It appears to follow that of Offer/Answer model variant. As per rfc3264 and the application section is “8.3.1 8.3.1 Modifying Address, Port or Transport ”:
I see the incoming 180 and 200ok have different IP address and ports of which would fall in that category. Also, the initial 180 has sendonly so it probably does not change from that.
This would have to be raised as an FR to a dialogic sales team to determine if enhancement can be done to add this functionality.
Regards,
Jeff
