Can some explain how to resolve the subject issue? VVX300 phones can dial 3-digit extension to any phone including vvx500 ones. When 3-digit extension is attempted the result is silence. Paging works. All on same network.
welcome to the Polycom Community.
It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.
This also allows yourself and others to check against current software release notes.
The above is also stated in the "Read First: Welcome to the Polycom VoIP Forum"
Therefore the Polycom VoIP FAQ contains this post here:
Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check here
In addition it is also useful to state what kind of SIP Server is being used.
Also is this Off hook dialing or On hook dialing ?
