asterisk users - Apr 2006 - Meetme codec translation and callerID library.

Can Meetme be made to work with G.729? (I gather not)

If a call comes in (internally or externally), the call comes in as a
G.729 call, which then re-negotiates to a G.711u call when if gets
transferred to a MeetMe room.

Is there a way to set up asterisk that will allow me to have internal
phones renegotiate to G.711, with the external lines instead transcoding
within asterisk.
(runtime is more available than bandwidth).

Also, does anyone know if there's a way to dynamically alter incoming
Caller-IDs to add Caller ID text to them.

ie. call comes in with ID 01234 567890 gets changed to "A Company"
<01234 567890> ?

This will be with a lot of numbers, so a pile of conditionals in the
extensions.conf file wouldn't really be a good solution.

IIRC, MeetMe does it 'mixing' using SLIN (Signed Linear, * should
transcode to/from g.729 to SLIN.

It sould be transcoded into SLIN from g.729. If you phone is requesting
the use of G.711 you may want to use a disallow/allow in your sip.conf.

I don't follow, You want the inside (high-bandwidth) phone to use G.711.
If so use the allow/disallow in sip.

Set(CALLERID(name)="What ever you want")

If you want Dbfunctions you could write an AGI script, or you can use
the DB function within Asterisk (ASTDB and *SQL) to set the variable.

Look at cid_rewrite, here:

You'll have to adjust the number formatting to fit your country's number
format, and simply turn off the web-lookups, which wouldn't work in your 
case.  You can then provide a list of calling numbers and associated 
names in a mysql table.
