I am trying to get Cisco Unity Voicemail working with * and
am having a slight problem. Essentially the setup is as
follows:
Broadvoice---asterisk-----Unity SIP VMail
Unity needs the following from * :
•![]()
In the Diversion header, the
extension of the called party
•![]()
In the Diversion header, the
reason for the forward (the extension is busy, does not answer, or is set to
forward all calls)
•![]()
In the From header, the
extension of the calling party (for internal calls) or the SIP URL of the
calling party (if it is an external call and the system uses caller ID)
Cisco Unity uses this information to answer the
call appropriately. For example, a call forwarded to Cisco Unity is
answered with the personal greeting of the subscriber. If the phone system
routes the call to Cisco Unity without this information, Cisco Unity
answers with the opening greeting.
How can I configure sip.conf and extensions.conf to supply this
required information? Is modifying the Diversion header done
with the Dial application??
Thanks in advance.
