[Serusers] Too Many Hops

[Matteo Piazza]

I have Ser and asterisk on the same machine.
When i try to call with a SIP phone registred on asterisk another sip 
phone also registred on asterisk through SER I receve this error message:
Too many hops
I not understand the reason.
Someone have an idea?
Thank's
