How to clear or disconnect a active call on a SIP IP to IP Gateway

[shargovi]

Hello,

 If you have any configuration modifications to make on a SIP gateway while a active call is there is not possible.For example if you are binding you will get a error

Note If there are active calls, the bind command will not take effect if it is issued for the first time or if it is issued while another bind command is in effect. A message is printed reminding you that there are active calls and that the bind command change cannot take effect.

For example :

dial-peer voice 15 voip

description outbound dial-peer to CUCM

voice-class sip bind control source-interface GigabitEthernet0/0

voice-class sip bind media source-interface GigabitEthernet0/0

dial-peer voice 1 voip

description inbound from CUCM

voice-class sip bind control source-interface GigabitEthernet0/0

voice-class sip bind media source-interface GigabitEthernet0/0

dial-peer voice 2 voip

description inbound from ITSP

voice-class sip bind control source-interface GigabitEthernet0/2

voice-class sip bind media source-interface GigabitEthernet0/2

dial-peer voice 20 voip

description ***outbound dialpeer to ITSP***

voice-class sip bind control source-interface GigabitEthernet0/2

voice-class sip bind media source-interface GigabitEthernet0/2

Can anyone let me know any command or way to clear or disconnect the active call to do the changes without reloading the gateway ???

We may achieve this by the following sequence of commands:

++ BIG520#show voice call st
CallID     CID  ccVdb      Port        Slot/DSP:Ch  Called #   Codec    MLPP Dial-peers
0x1A2      1468 0x8AA3F248 50/0/22.0                2113       g711ulaw  4 20021
2001920021/20019
0x1A3      1468 0x8B2611CC 50/0/11.0               *2113       g711ulaw  4    20019/20021
20019/20021
1 active call found

Router#clear call voice causecode 2 id 1468

(here 1468 is the CID mentioned in the show voice call st)
