[Asterisk-Dev] ${RDNIS} from SIP-GW

[Christoph Frei]

Hello,

i'm trying to get a virtual voicemail done by using RDNIS. I can see with
sip debug that the gateway sends a header with the correct number:

Diversion: <sip:012345678 at 192.168.1.1>;reason=unconditional

Is this simply not yet supported by asterisk, or do i have to activate 
the RDNIS
feature on SIP somehow? ${RDNIS} is always empty...


Greetings,

Christoph
