| Title |
Calls for Mobile Voice Access through an H.323 IOS gateway do not work when Cisco MobilityManager is used. Cisco CallManager does not send the correct called number to the gateway. The Q931 traces show a "Disconnect cause code: ISDN Se2/0/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x009D Cause i = 0x80A9 - Temporary failure" error message |
| Core Issue |
In this scenario, the setup involves a Primary Rate Interface (PRI) through which the call comes into the Cisco IOS® gateway. From the gateway, the call is transferred to a VXML script that transfers the called number to the Cisco MobilityManager. The Cisco MobilityManager then sends the call to the CallManager, which sends an H.323 call to the voice gateway.
The problem in this case is that for every call that is made through the Cisco MobilityManager, the CallManager sends the same called number. When option 1 is pressed in order to make an outside call, the call is disconnected by the H.323 gateway after four seconds. |
| Resolution |
In order to resolve this issue, perform these steps:
- Make sure the H.323 gateway has the VoIP dial-peer pointing to the Computer Telephony Integration (CTI) ports correctly, as detailed in Configuring H.323 Gateways for Mobile Voice Access.
- Disable the H.323 gateway for Inbound FastStart in the Cisco CallManager administration.
