This is the current scenario:
We have a 3745 MGCP gateway receiving calls from the mobile prover over isdn links. We have a Voicemail server connected over isdn links on a 2nd 3745 MGCP gateway. Incoming calls from the mobile network ring on an extension first and are then sent to the voicemail server. The voicemail server recognises the extension's voicemailbox from the redirecting number. Callmanager version 4.1(3) and this scenario works fine.
Now the mobile provider will soon present the redirecting mobile phone's number in the isdn redirecting number field and we want this to be passed to the voicemail server in addition to the extension's redirecting number.
I would much appreciate if anyone knows a scenario how I can make this work.
