Maybe this has been discussed, or I'm missing something obvious. I built my corporate system on 4.0.4. I wanted to use G722 internally, G729 for external, and the ability to renegotiate to G711 if ITSP (Verizon requested it). Verizon doesn't do G722, so simply putting the codecs at the phone group to 722, 729, then 711 worked perfectly. We upgraded to 4.2.1 a month or so ago. We started going over our allotted bandwidth on our VOIP circuit and dropping calls. After looking at a wireshark, I saw that all calls were using G711. I poked around and found this new (I think it is new) feature: Devices, SBC Routes, sipXbridge-1, SIP, Show Advanced Settings ,Permitted Codecs The default setting was "PCMU,PCMA,G722,L16" On a test machine, I blanked this field, and now calls are using G729 as expected. If I understand it correctly, the upgrade puts in a default setting that will not allow sipXbridge to use G729. If that is the case, wouldn't the safer thing been to leave that field blank and maybe advise the user of the new feature? Am I correct that blanking out that field should make sipXbridge behave more like 4.0.4 with respect to codec negotiation?
