[SIP Beyond VoIP] Address through SylkServer

I think I have mostly solved my problems with the session establishments, at least from the SIP/MSRP direction towards the XMPP server. And basically you guys were right that the client I'm using is not sending the invites correctly. I will have to deal a bit later with that, together with the XMPP -> MSRP sessions.
However I have another problem now.
I'm trying to make the following message flow: SIP/MSRP -> SYLK -> XMPP Server -> XMPP Backend for Facebook -> Facebook. That's almost possible to be done, but the main problem I'm having is when I want to address message towards FaceBook user.
Currently facebook users appear in XMPP world if a backend is used the following way ( and we know they do not support federation )
-739277318\40chat.facebook.com at facebook.testing.com
What I'm having as a problem of course is the address and particularly the "\" char over there. Do you have idea how the backslash should be represented correctly? As when I enter it as a escape character, Sylk Server complains about the SIP addressing:
I'm entering the address the following way:
-739277318%5C40chat.facebook.com at facebook.testing.com<mailto:-739277318%5C40chat.facebook.com at facebook.testing.com>
Then Sylk complains with the following errors:
[xmppgateway] New incoming SIP MESSAGE from sip:alice at open-ims.test
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/twisted/internet/base.py", line 766, in runUntilCurrent
File "/usr/local/lib/python2.7/dist-packages/sylk/applications/__init__.py", line 137, in handle_notification
File "/usr/local/lib/python2.7/dist-packages/sylk/applications/__init__.py", line 196, in _NH_SIPIncomingRequestGotRequest
File "/usr/local/lib/python2.7/dist-packages/sylk/applications/xmppgateway/__init__.py", line 172, in incoming_sip_message
recipient = Identity(FrozenURI.parse(to_uri))
File "/usr/local/lib/python2.7/dist-packages/sylk/applications/xmppgateway/datatypes.py", line 62, in parse
raise ValueError('invalid SIP uri: %s' % value)
ValueError: invalid SIP uri: sip:-739277318\40chat.facebook.com at facebook.testing.com
And at the end basically in the Sylk ( started with -no-fork ) the Value Error represents the address which I want to see sent towards the XMPP server
