[Asterisk-Users] best low-bandwidth strategy

[Louis-David Mitterrand]

Hi,

To push voice through a long thin wan (dsl) there are two choices: 

(1) have the cisco's (7912G) talk g729a to each other (reinvite=yes), or

(2) have the cisco's talk to their local * in ulaw (reinvite=no), which
talk to each other through a more advanced low-bandwidth codec (ilbc or
speex)

which is best? (2) would have more latency, wouldn't it?

Did I miss a third option?

Thanks in advance for you insights,
