hi all,
can you tell me what are the cause to reject the call which in ISUP RELEASE message cause value 31?
Routing Label:
(DPC) Destination Point Code: 02069
(OPC) Originating Point Code: 02014
(SLS) Signalling Link Selection: 4
(CIC) Circuit Identity Code : 0E4h = 0228dec = PCM: 7 TS: 4
RELEASE
Cause Indicators
coding standard : CCITT standard
Location : 3 = transit network
cause value : 31 = normal event – normal – unspecifiedThis cause is used to report a normal event only when no other cause in the normal class applies.
What kind of event that is categorized normal in this case? Are there any example events?
Hi there,i also have have a problems with cause value 31..Actually what is the cause of this problem?
Cause 31 is kinda associated with interoperability issues. For example when two local networks are using different mechanisms (routing tables, numbering plan, different bearers ( for example one is using a circuit & packet switched 3G network and the other an entirely packet switched 3.75G network with an IP-based Gb interface)
