Okay, here's a good one... If you take a Cisco and make it g729 only, dial call one on line one, then press Conf, dial another call, it won't connect. You get a reorder message/tone and the console shoots out "No compatible codecs!"
So I thought, sure, I guess that makes sense only one g729 call per line on the Cisco, I guess that makes sense. But, you can pick up line 1, make a g729 call, put it on hold, make another g729 call, put it on hold, go to line two and do the same thing, your console will show all four g729 calls at once, though I guess you're not talking on any at the same time, so maybe that's the loop hole. Anyway, I could enable ulaw to make the conferencing work again but if you have ulaw enabled at all, it seems to force the calls to go ulaw first even if g729 is first in priority in the show sip peer xxx output. So you lose the whole benefit of using g729 and saving your bandwidth completely. So, is there a work-around to make g729 work all of the time except when I'm conferencing or make it work all of the time, period? Also, I've only tested this on a 7940, so a 7960 may not have this issue. Thanks in advance for any advice - Ian
