Issue Description

Device : MA5620

Version : V800R312

ISSUE : when user dial a extension and press # to make it dial immediately the call gets disconnected, where the same thing works on ONT under same OLT/IMS

Topology :-

From ONT to MDU

1. user dial 55555 and press # the call is normal and MDU user receive the call

From MDU to ONT

1. user dial 99999 and press # the call is disconnected


 

Alarm Information

User call From MDU 55555 to ONT 99999

1. user dial 99999 and press # the call is disconnected

Handling Process

From MDU 55555 to ONT 99999

1. user dial 99999 and press # the call is disconnected

Handling :-

2. Filter the packets using Filter : sip

3. check the packets

 

 

4. When the user dial 99999# the character # will transfer to %23 as default, which the IMS/SIP SERVER/PROXY Server does not recognize

5. Add configuration on MxU to make it normal

  a) add digit map

MA5620(config)#local-digitmap add normal normal [xABCD].S|[xABCD].#

MA5620(config)#local-digitmap add scc scc [*#][*#0-9][0-9*].#|##|**xx|#*#

 

 b) change the interface sip para

MA5620(config)#interface sip 0

MA5600(config-if-sip-0)#mg-software parameter 13 0

MA5620(config-if-sip-0)#if-sip attribute basic sipprofile-index 0

MA5620(config-if-sip-0)#sipprofile modify syspara 72 2

MA5620(config-if-sip-0)#sipprofile modify syspara 142 1

 

 c) reset the interface sip

MA5620(config-if-sip-0)#reset

 

6. Test the service and capture again to find the normal pattern
