[SR-Users] How to change MSRP from sip address?

I need to replace the "From" address of MSRP message with something different. I noticed that module does not allow one to set values from config file. What does it take to enable this functionality? Does anyone have a prototype I can leverage? Need to replace from domain with some other domain - Given: MSRP body is - From: cust3 <sip:cust3@devtranslation.sms-test.cyracom.com>#015#012To: <sip:agent1@xmpp.xgw.cyracomdev.com>#015#012DateTime: ..... Wanted: MSRP body is - From: cust3 <sip:cust3@new domain >#015#012To: <sip:agent1@xmpp.xgw.cyracomdev.com>#015#012DateTime: .....
