[Spce-user] CE 2.6: Call-forwarding to voicebox via VSC

[Klaus Peter v. Friedeburg]

Hello Andreas 

Thank you for your reply.
In my installation it is a little bit difficult:
In Germany the Bundesnetzagentur don’t allow to use own "number-assignment" so that I have defined "*2000 " as my system wide voicemailnumber. (in the config as \*2000)
But there exist the problem that vsc-dialing *72**2000 does not work - sems ignore it. The other problem is, that same clients don’t dial the *2000 correctly. 
For the problems I have defined a inbound rewrite rule for callee  in domain to rewrite the dialed number 2000 to *2000 so that you can dial the vsc *72*2000 or dial 2000 to reach your own voicebox
This rewrite rule is also using by sems. Sems rewrite *72*2000 to *71**2000 and inster "sip:+*2000 at ....! in die cf_set
In /etc/sems/etc/sw_vsc.conf there exist a line 
	voicemail_number = \*2000

dpkg -l|grep ngcp-sems give me this lines:
ii  ngcp-sems                                  1.4.3+spce2.6.2              SIP Express Media Server, very fast and flexible SIP media server
ii  ngcp-sems-prompts                          0.3.1                        Audio prompts for ngcp-sems package
ii  ngcp-templates-ce-sems                     2.6.17                       Configuration templates for ngcp-sems
