Hello everybody,
I have a simple voice network setup:
SIP trunk -------- ISR 2821 (IVR) ----------- CUCM 7.1.3
On the ISR 2821 IVR script is installed. After receiving incoming call, IVR plays the prompt.au and disconnects.
The same script works fine on the PRI line of the mentioned voice gateway.
I provide the partial configuration of the ISR and upload installed IVR script.
!
application
service ivr flash:ivr.tcl
!
dial-peer voice 191 voip
service ivr
session protocol sipv2
incoming called-number 3547777
codec g711ulaw
no vad
!
I will be grateful for any help and advice.
Kind regards,
Lidiia

whats the protocol you are using between sip provider to 2811 and 2811 to cucm?
You may need to add following
voice service voip
allow-connection sip to sip
allow-connection sip to h323
allow-connection h323 to sip
allow-connection h323 to h323
!
Thanks

Hi Abu,
Thank you for your reply.
You right. H.323 works between CUCM and 2821 gateway.
SIP ISP ------ 2821 Voice GW ----- (h.323) ----- CUCM 7.1.3
But I have the configuration you wrote about.
!
voice call send-alert
voice rtp send-recv
!
voice service pots
!
voice service voip
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
no supplementary-service sip moved-temporarily
no supplementary-service sip refer
fax protocol pass-through g711ulaw
h323
sip
registrar server
!
If you have any thoughts how to troubleshoot such type of problems, please, write it to me.
Thank you!

Hi All,
We resolwing this issue by upgrading IOS on GW. Current version is
c2800nm-adventerprisek9_ivs-mz.151-4.M1.bin
Configuration remains the same.
P.S. Don't forget to add
voice service voip
no ip address trusted authenticate
because, by defaul, 15.x IOS accepts calls only from trusted peers.
