Convert 7821 phone from ent into MPP to register with 3rd party PBX

[Hythim Ali El Hadad]

Hi

I have 7821 IP Phones and need to register it to 3rd party PBX. We need to be able to configure it through web browser. Not through the XML file

I see we can convert our 7821 into MPP firmware provided it is V03

I need to ask if this requires license as:  L-CP-E2M-78XX-CNV=

Or I can test the conversion without any license

Also is this one time conversion ? So I won't be able to convert it back to enterprise ?

Thanks

Yes you do need a license.

No. You cannot convert without license. Both side conversion is possible, but it requires license for every conversion.
