Inbound Routes patten matching issue

I am working on a PBX system in Italy and having issues matching an inbound call to an extension due to the way the sip provider is sending the call.

Looking at the output of asterisk -rvvvv I see this:
– Executing [+3907751437197;trunk-context=3907751437197.ims.vf.it;tgrp=tg3907751437197@from-pstn:1] Set(“PJSIP/vodafone_pjsip_1-0000007b”, “__FROM_DID=+3907751437197;trunk-context=3907751437197.ims.vf.it;tgrp=tg3907751437197”) in new stack

My inbound route DID is set to 07751437197 but because my sip provider is formatting the call in from the trunk as
+3907751437197;trunk-context=3907751437197.ims.vf.it;tgrp=tg3907751437197@from-pstn:1 - the pbx does not know where to send the call and says “the number you have dialled is not in service”

I need to edit the way the call comes in from the trunk so it is formatted as: 07751437197@from-pstn:1

Can anyone help me with where I would need to configure the incoming call to strip anything except the last bit 07751437197@from-pstn:1 so that it matches my inbound route (DID: 07751437197 --> EXT:1234)

Thanks
