To be SIP correct, a proxy may not insert any transactions in a dialog between two endpoints. The endpoints have the cseq counter and inserting anything will mess with the CSEQ.

Having said that, the dialog module has a keep-alive function that does this. It may generate strange error messages which is fine. You want to test the behaviour on a per-device basis.
