Debugging VOIP with Shikha Sharma #CiscoKid

For such an issue, please make sure SIP domain IP address is correct.

Try the following steps- Open CMD and restart WWW and IIS. net stop w3svc net start w3svc iisreset /stop iisreset /start Generally in such a scenraio, you have to start iis twice because it will fail at the first. If WWW service is stuck on stopping, you may kill the service using the following command- taskkill /F /FI "SERVICES eq w3svc"

To reset all dsp resources- Router#test dsp device <pvdm slot> all reset To reset one dsp resource- Router#test dsp device <pvdm slot> <dsp> reset Please note that rebooting won't reset the DSPs. A few reason codes which needs dsp reset is if there is congestion on our equipement or if we don't have resources available. Cause code 0x80 shows issue on the router on our end. Cause i = 0x80AA -  Switching equipment congestion Cause i = 0x80AF - Resource unavailable , unspecified

Its good to write again. Had to take a break in between but it got longer than I thought. Anyways, getting back to our query of the day, I think it would be helpful for many engineers while dealing with this piece of information. I faffed on google too but there was no information on how to check hardware model from windows call manager as nobody was at site While clutching at the straws, I was browsing regedit and it came across. Here is the path- HKEY_LOCAL_MACHINE > Software > Cisco Systems > Model- Hardware. I hope it will help you too.
