U1930 intro-offcie phone make a call forwarding to PSTN failed

Publication Date:  2014-12-14 Views:  26 Downloads:  0
Issue Description
U1930 connects to PSTN through PRA trunk. the intra-office phone A registers the service about call forwarding to mobile phone B. then the PSTN user calls to VU and choose extension phone A. the mobile phone B does not ring.
U1930 version is  V100R001C01SPC900.
Alarm Information
none
Handling Process
test as below:
1. phone A directly calls to B, B rings.

2. use a intra-office phone C to call A, B also rings.

3. use another mobile phone to call A, B does not ring. we doubt this issue has somthing to do with the VU and trunk outgonging call authority.

4. check the soft parameter 378, do the command:
    show softargu configinfor id 378
    we check the value is default 0, this means the VU trunk can not make a out going call to PSTN.

5. do the command:
     config softargu type 378 value 1
     give VU trunk the authority to make a out going call to PSTN

6. do the command:
     show trunkgroup
     we can check the PRA trunk GroupNo is 6098. it does not have the authority to make a out going call to PSTN.

7. do the command:
     config modify trunkgroup no 6098 restrict Yes outgoingright Inter&Local 
     give the PRA trunk authority to make a out going call to PSTN.

8. repeat testing. now it is ok.
Root Cause
the VU and the PRA trunk both do not have the authority to make a out going call to PSTN
Solution
as above

END
