CUCM7 sip trunk to 3cx via CUBE

Hi there,

Please help me with my issue.

There are 2 separate parts on single building , each one has own VOIP implementation. 1 part VoIP is based on CUCM7 and another one works with IP PBX 3CX. CUCM and PBX system have 4 digit extensions (1000-8999) Now I'm trying to connect them through CUBE wich 2811 ISR router.  

CUBE reaches to CUCM and IPPBX through 1 fa0/0 interace with ip address 10.21.3.151

3cx 10.21.3.150

cucm 10.200.3.2

In 3CX side i configure Gateway with 10028 username. this credentials will be used to register sip-ua for CUBE.  and from cucm estabilished sip-trunk to cube. 

here is conf of cube:

Hi Carlo, thank you for your

Hi Carlo, thank you for your reply.

when create any gateway or trunk 3CX system gives for it 5 digit extension number and it's normally not available when you call to this number directly it is only gateway i.e. 10028.  so in 3cx system, status of this gateway   is registered.

and in cube show sip-ua register status  is registered. 

sh sip-ua register status
Line                             peer       expires(sec) registered P-Associ-URI
================================ ========== ============ ========== ============
10028                            -1         204          yes   

in cucm side extension number 1126

and 3CX's extension 1297

Hello Carlo.here is log files

Hello Carlo.

here is log files from 3cx and cube when i try to call from 3cx internal extension 1297 to CCM extension 1126 via CUBE gateway. I still get 404 not found message.

ip addresses are:

3cx 10.21.3.150

cube 10.21.3.151

ccm 10.200.3.2

CUBE available for 3cx and ccm from single interface 10.21.3.151

3cx trunk with CUBE via SIP with credentials 10028 and 3CX  is registrar.

Dial peers not clear for me.

Best regards,

 

 

I think you dont need

I think you dont need username and password inside local network

unnecessary complication

 

and also it is possible to connect cucm to 3cx directly. without cube

I am trunking CUCM directly

I am trunking CUCM directly to 3CX as well.  I have found that I can call from 3CX to CUCM fine, but from CUCM to 3CX calls fail.

Calls from CUCM to 3CX are getting a 407 Proxy Authentication Required from 3CX.  If there is not a SIP Realm defined in CUCM then CUCM just drops the call.  If I add the "3CXPhoneSystem" SIP Realm then CUCM will respond to the 407 with the username and password that are defined in the SIP Realm.  However nothing that I put in the username and password field works - I always get a 404 User Unknown.  I've tried extension credentials and virtual port credentials, but it never works.

Do you have required

Do you have required configuration in place including application user?
