Increase in wait time of synchronous interface

I am working on HTTP to proxy synchronous interface on PI 7.3

PI uses communication channel with SOAP receiver adapter over XI protocol

Now I am facing below error in the interface while testing after 3minutes-

      com.sap.engine.interfaces.messaging.api.exception.MessageExpiredException: Message (INBOUND)expired

Can anyone please tell me how can I increase wait time in the channel.

I have tried adding the parameter name 'XMBWS.Timeout' and parameter value '30000' to increase wait time to 5minutes. But it didnot work.
