[Serusers] ERROR on Request line ACKNOWLEDGE

HI,

 

I have an interconexion with a proxy-server registrar IPTEL to a Cisco
GATEWAY AS5300 for the PSTN.

 

When I make a call by a Cisco IP phone, I have no problem but when I make a
call with a call-box(Same as Cisco ATA) or a softphone Xpro (XTEN), I can
speak 20 s and after the call is cut.

 

I have analysed this problem, the problem is after the SIP ringing frame,
the softphone send a SIP frame ACK with a bad request-line.

 

IP ADDRESS 80.118.128.1 : CISCO AS5300 GATEWAY

IP ADDRESS 80.118.128.5 : SERVER IPTEL

 

The RED parameter in the first DEBUG is BAD, he as to be as the same of the
second debug.

 

That's my debug of the SOFT PHONE: BAD ACKNOWLEDGE
