[SIPForum-discussion] Sip 400 Bad Request

[Ryan Merideth]

Looking for help for an INVITE header problem. Customer sends us an INVITE
and our network returns an immediate SIP 400 bad request. I have deteremined
that this line is what our switch does not like (Route: sip:10.32.202.54;lr)
but I do not know why. Any ideas? Thanks in advance.

Ip's and personal information has been changed:
