You can try to nudge it that way somewhat. First off, you'll need to set 
"autoframing=yes" in the sip.conf general section. This will allow for 
the ptime sections of SDPs to be honored. Next, when defining your SIP 
peers, you can specify allowed codecs like so:

allow=ulaw:10

This way, the ulaw codec will be offered with a suggested ptime of 10 
instead of the default 20.

Give these things a try. They may be all you need and you may not need 
to alter code any. The problem is that you may find implementations will 
still send you 20 ms segments even though you requested 10.
