To locate the registration problem, you must clearly specify the number of the registered device and the corresponding IP address.
I. Registration problem location in H323 scenario
If the H323 registration fails, the CS is checked whether the SC has received the registration request. If the registration is replied to the RRJ, the device can rarely carry the specific cause. You need to perform the location analysis through the SC device log and the prompt on the terminal.
To filter the registration information of the terminal, first filter by filtering h225 and terminal IP address.
1. RRQ signaling
2. RRJ signaling
For example, here is 69H, reference error code document http://3ms.huawei.com/km/blogs/details/2497533
As err_desc.txt, as can be seen from the document, the general description of 69H is that the alias has been used.
Or refer to the terminal interface to maintain à system status.
3. RCF signaling
There is no important information in RCF. Whether it supports H460 will be carried for SC.
