[OpenSIPS-Users] validate_dialog() failing to recognise reinvites

[Kingsley Tart]

Hi,

Thanks. I hadn't noticed before but yes, I'm seeing this:

ERROR:dialog:dlg_validate_dialog: failed to validate remote contact: dlg=[sip:asterisk at 1.1.1.28:5060] , req=[sip:asterisk at 1.1.1.28:5060;user=phone]

I can't see anywhere in the SIP trace where that contact URI appears
*without* user=phone in it so I don't understand why that's happening.

Cheers,
Kingsley.
