[OpenSIPS-Users] Cisco "483 Too Many Hops"

[Julien Chavanton]

Hi, I have a situation where Opensip is fowarding to a Cisco box, the Cisco is returning :

	SIP/2.0 483 Too Many Hops 

If I dial from a registered sofphone the remote cisco accept and answer the call

I am wandering why the Cisco find a loop whe receiving this invite, I guess this could be related to the Via headers :
