I am trying to make a sip call from uc500 to ASTRIK which iam connected to it throw site to site vpn.
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)
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
There is nothing you can do about on the UC500.
You are calling 618 correctly but asterisk replies that it doesn't know this number.
It's up to them to fix the problem. Unfortunately often people using "free" solutions don't really know how to do things.
