No Ringback tone via ABCF IP TG then VPN Overflow on IP

[William084]

No ringback tone calling from Site A to Site C.

I here one ring then silence when the call is answered the coversations it ok

Using Direct RTP

All other calling directions work fine. A to B, B to A, C to A, C to B

Site A--ABCF IP TG to--Site B-- VPN Overflow on IP to Site C

3 x V9 oxes, 2 subnetworks

Site A, V9 31b, Network 1
Site B, V9 42a, Network 1
Site C, V9 42a, Network 2

I have done some testing now looking for a fresh idea

Any suggestions??

Thanks for your feedback...

Narrowed the issue to the ABCF IP parameter "Homogenous Network for direct RTP" when I invalidated the parameter the symptom went away.

Logged an eSR after working with the BP and Alcatel R&D, Alcatel produced a "Hotfix" to suit V9 42a.

Vois la, all works now.
