I have an ACS 2.4 which is configured to screen the caller id incoming to the NAS Cisco3640.
The problem is that some ( maybe 5 of 100) of the incoming calls will be denied . When they tried it a second time, the incoming call will passed without problems.
When i debug this, i will see in Q.931 that the calling and called party number is transmitted (incoming)
Calling Party Number i = 0x2183, '47114711', Plan:ISDN, Type:National
Called Party Number i = 0xC1, '11471147', Plan:ISDN, Type:Subscriber(local)
but in the outgoing T+ message to the ACS will be only a 0X00 for the rem_addr
(for these i receive "authen response status fail")
T+: rem_addr: 0x00 0x00
when they tried it a 2. or 3. time it will be o.k
T+: rem_addr: 47114711/11471147 0X00 and i receive
TPLUS: Received authen response status PASS (2).
Can somebody give me a workaround or solution for these problem.
Thanks
Andreas
