No AVPs or vars. The encoding field separator can be specified via params:

Thanks Guys, I'll be trying this. Do you know if I
can use AVP or vars as
parameters for these functions?
encode_contact(encoding_prefix)
decode_contact()

The best would be to tell the providers that they should fix their
systems.
As a workaround you could try encode/decode contact functions:
http://sip-router.org/docbook/sip-router/branch/master/modules_k/siputils/s…
IIRC these functions may cause strange results if you do other contact
rewriting too (e.g. fix_nated_contact).
