The phone was power cycled to get the new settings.
All phones can place and receive call, can transfer etx. I’m trying to integrate Asterisk voicemail with Cme 4.1


--- Asterisk 1.8 FreePBX Config

Using Webmin-Filemanager-Edit, I added the following lines to /etc/asterisk/extensions_custom.conf

Number that CME dial to access voice mail when the message button is depressed on the IP Phone.
exten => 3999,1,VoicemailMain(${CALLERIDNUM})
exten => 3999,2,Wait(3)
exten => 3999,3,Hangup

;Number that CME dials to forward voice mail to Asterisk
exten => _3XXX,1,Setvar(ext=${EXTEN:1})
exten => _3XXX,2,Goto,vmail|s|1



Using FreePBX, I created a SIP trunk to CME’s Voice VLAN.

Trunk Name: DestoCME

Peers Detials
Host = 192.168.8.1
Type = friend
Qualify = yes
Context = cme-trunk



Using Free PBX, I created an outbound route to the CME trunk created previously:

Add Route:

Route Name: CME
Dial Patterns: 32XX

Truck Sequence: SIP/cme -trunk

Everything else defaults


For the CME voicemail extension, I created a corresponding SIP extension in Asterisk PBX with no secret

(Extension password), a DID number, enable voicemail services and check the NAT settings:

Add Sip Extension

User Extension: 3231
Display/ Name: CME3231

Add a DID entry with a prefix of 3 and leave the secret blank (no password):

Did Description: CME3231
Add Inbound DID: 3231

I enabled voicemail

And set Nat = no

My Problem:

When I press the voicemail button on the Cisco 7960 or dial the voicemail extension 3231 it display “Host cannot be found” on the phone
There seems to be no connection between the cme and asterisk
My question do I need a second sip-ua connecting the Cisco CME to asterisk?

Any ideas will help

Thanks again.
