Registering an IP Phone thru a WAN using CME

[jose_gomez]

Can I do this?

If yes, Can I configure it to use G729?

Regards, Jose

jose,

cisco design says not to configure any remote location phone using cme.

But yes techinically you can configure it.No CME phones supports locally g729 codec. so u cannot use it.This is the only reason why i feel cisco doesnt recommends to use phones across.

K.Vishwesh is incorrect.

You can perfectly deploy remote phones with CCME and Cisco has never recommended against.

From CCME 4.1 Datasheet at:

Remote tele-worker IP phone support

Link to configuration guide for remote phones:

Also stating that the phones do not support G.729 is oncorrect. To the contrary, all telephones do support it.
