SIP Trunk for incoming call from SIP Provider

[scr.sybex1]

Dear,

I am new to Collab World.

My Scenario is

SIP Provider----(SIP Trunk)------VGateway---------(H323)--------CUCM10.5.2-----------------UCCX

i want to configure incoming call to route to UCCX Application.

Please help to know what step i do to configure this scenario.

the configuration that i do and debug that i have is like this:

*Feb 26 07:05:51.337: //-1/D76F9A3FB434/SIP/Call/sipSPICallInfo:
The Call Setup Information is:
Call Control Block (CCB) : 0x0x229D4580
State of The Call        : STATE_DEAD
TCP Sockets Used         : NO
Calling Number           : 2177622027
Called Number            : xxxxx
Source IP Address (Sig  ): 10.194.10.6
Destn SIP Req Addr:Port  : 10.105.40.11:0
Destn SIP Resp Addr:Port : 10.105.40.11:5060
Destination Name         : 10.105.40.11

*Feb 26 07:05:51.337: //-1/D76F9A3FB434/SIP/Call/sipSPICallInfo:

dial-peer voice 21 voip
 session protocol sipv2
 incoming called-number xxxxx
 dtmf-relay rtp-nte sip-notify
 codec g711ulaw
 no vad
dial-peer voice 23 voip
 destination-pattern xxxxx
 session protocol sipv2
 session target ipv4:CUCM-PUB
 dtmf-relay rtp-nte sip-notify

 destination-pattern xxxxx
 session protocol sipv2
 session target ipv4:CUCM-SUB
 dtmf-relay rtp-nte sip-notify

and i Configure a SIP Trunk from CUCM to Router with defaullt sip profile and security profile on CUCM 10.5.2

In call flow, you have mentioned h323 protocol b/w CUCM and VG...dial-peer pointing towards CUCM is using  SIP protocol....I assume its using SIP protocol.

can you make a test call and collect logs of debug ccsip messages from SIP gateway

Make sure the Calling Search Space applied to the SIP trunk lists the partition assigned not only the CTI Route Point pointing to the application, but also your CTI ports used by CCX.
