Re: sip server through site to site VPN

Thank u man the errors goes away ..

any way i was doing somthing stupied by trying to dial from my 7940 phone without change it to sip ..i have tried alot of cisco guides to convert 7940 to sip but nothing worked out may be its the UC500.. attached is my running config ..

in my phone when i check status from Network configuration i have VERSION 8.0(5.0)

i follow this link

and do every step to change SCCP to SIP

but nothing work out... i dont know if i need to downgrade from SCCP 8.x to 5.x then upgrade to sip 4.x ... and is the firmware in call manager same as call manager express or uc500
