sip incoming issue

[sadim]

Hi again.

Meanwhile I have another idea that should work. In OXE, the maxptime is 30 for the G711 and 40 for the G729. So if you manage
the sip connection so that the only codec is G729, in the traces you should see the maxptime at 40

hi Sadim. yes you are right. in codec g729 the maxptime in 40. but unfortunately the sip provider uses only g711. as for sbc, we do use a cisco 1921 router as a sbc. it works fine for many installations with sip. i have never tried alcatel sbc or any other..

Hi,
As far i know, cisco 1921 does not implement CUBE features

hi
i have seen in the forum such as solution especilay in ksa, they use Cisco routers as SBC

Got it working,,,
the RBT is working now. the provider dont send the Require: 100rel for some out going calls. so the OXE dont send the PRACK and no RBT for those calls. what we did we set as not supported for out going, now the RBT is ok for all. still testing though..

thanks for all the once who supported on this....
