[cisco-voip] Jabber region restriction issue

[Bernhard Albler]

looking at your invite it looks like an MTP is being invoked ( assuming .2
is the address of a cucm node)
Thats the reason g711 is being used
now the question is if the MTP was inserted via config or because of some (
e.g. dtmf) other reason and if it is safe to remove it therefore...
