OK I got a RealPresence Trio 8800 that is registered to my Cisco Call Manager 10.5.2
I can dial our internal 5 digit extensions, but when someone answers the phone gets a busy tone.
I also have busy tones when trying to dial outside calls. Not sure what type of info I need to give to help out with this.

Hello adivac730,
welcome to the Polycom Community.
It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.
This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.
The above is also stated in the "Read First"
Therefore the Polycom VoIP FAQ contains this post here:
Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here

Hello adivac730,
Following the previous outlined FAQ will enable you to log the issue. You can then share the logs with us.
- Settings > Logging > Global Log Level Limit > Debug
- Settings > Logging > Log File Size (Kbytes) > 512
- Settings > Logging > Module Log Level Limits > SIP > Debug
If you are unable to do this then you need to open a support ticket.
In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.
If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you.
