Hi all,
I have one Cisco Voice gateway with one E1 connection. I am using a TCL script auto attendant. However, incoming calls don't get any ring back tone util IP Phones answer. Any ideas for me?
Thanks,

I'm not well versed in TCL, It seems the prob in the SIP sessions. Can u enable PRACK on the Dial peer and the SIP profile associated SIP trunk and chk. U can enable by folowing the below steps.
CUBE
dial-peer level:
dial-peer voice XXXX voip
voice-class sip rel1xx require 100rel
CUCM
Device -> Device settings -> Sip profile -> Trunk Specific Configuration
SIP Rel1XX Options Required Field : Send Prack if 1xx contains SDP
Thx

Thank you for reply.
I test my system again and see that there is just not busy tone if the destination is talking .
I found that I missed en_reenter_dest.au file in the flash. When my destination is busy, procedure act_Select will be triggered. So, the TCL script plays this file. Now, it is fine.
Thanks,
Thuc
