Hi, I've a Cisco UBE that receive a SIP calls from a remote provider. This provider send ANI-II Digits into a From header like:
Received:
INVITE sip:62501@xx.xx.xx.xx:5060 SIP/2.0
From: <sip:477399@xx.xx.xx.xx:5060>;isup-oli=00;tag=SDs1ts901-10.50.83.40+1+161e1d+61e8c298
but when CUBE pass-through this call it strip ANI II Digits
Sent:
INVITE sip:601@10.xx.xx.xx:5060 SIP/2.0
From: <sip:477399@10.xx.xx.xx>;tag=850A3664-1051
Is there any way to avoid this? I need to pass-through ISUP-OLI on From header.
