How to Register a Grandstream ATA to Cisco Call Manager 12.5

[@marcvillanova5111]

I have been fighting with the device for the past 2 months. Everything right except for the SIP User ID. Thanks for a great video.

Thanks Marc! Glad it helped you. Let me know if there are any other voice related videos you would like to see

[@mayurparekar3838]

What license is used on Cisco Call manager for the Grandstream phone? Enhanced or Basic?

[@prathapreddy1049]

Could you please explain about WebEx calling and Cisco cloud

[@simpleciscovoicetutorials79]

Thanks for your request! That is something I am looking into for a client and will post a video about it if I am able. Thanks for watching.

Bro, is Cisco going to stop cucm service?

[@simpleciscovoicetutorials79]

I do not see that happening for a LONG, LONG time. So many people are using CUCM. But I am sure they are going to try to push everyone to the cloud.

I'm having problems, on a Cisco ATA 191, it doesn't register with CUCM, it shows the following error log, tftp download file , download loads file, (CTLSEP XXXXXX.tlv) fail ! in the case XXX would be the MAC of the device, I left it generic here in the explanation Anyone got this error?
