Incoming SIP calls to UCCE rejects with cause code 127

this is the call Flow

SIP VXML Gateway------->CUPS-------->CVP----->ICM---->CUCM--->AGENT. Then CUPS is acting as proxy server

 

The Call from new SIP trunk , is received by CTI agent desktop and reserved ,but unable to reach agent phone and disconnects the calls after 18 secs with cause code reason q.850 cause=127

But the call is working fine trough analog lines which is connected to teh same gateway. So please advice

Hello, To better understand,

Hello,

 

To better understand, is the problem only when the call is not recieved by Agent, can you hear WAV, is the Send to VRU node successful?

Hi

Hi It seems call routing to ip phone is getting failed .Could you please check below mentioned points , 1 , confirm agent is using correct ip phone number as instrument in CTIOS . 2 , check device target / agent targeting rule ,whether its configured properly for CVP routing clients . 3, check static route in cvp , to route calls directly to CUCM / CUPS , if calls are routing from CUPS to CUCM , check static routes in CUPS too .

We have routed the SIP trunk

We have routed the SIP trunk call to CUCM ,- back to gateway via CTI route point. Now Everything is working fine
