So what codec supports mobile phones? jfenton wrote:
Hi Edmar,
I need actually G729 license if there's any for freeswitch to call mobile phones... I already load it but has an issue on it passthrough mode... If i install mod_dandhi_codec it overwrites the existing G729 without license to a new G729 with license?
Are you sure your mobile phones support G729? Most phones have hardware acceleration for AMR-NB and not G729, so most of the VoIP-over-WiFi providers use that codec instead. I believe G729 would have to be implemented in software only (without hardware assistance) and would drain the battery fairly quickly as a result.
As other have pointed out on the list, and just in case you missed it mod_dahdi_codec is for use with a PCI accelerator card (the TC400B) that Digium (http://www.digium.com/) sell and will not work without it. With that card you can get up to 120 concurrent G729A-G711 calls.
These days you can get much better performance from pure software codecs running on Intel/AMD systems than using the above card. We (Howler) happen to have announced a G729A codec for FreeSWITCH a few days ago - you can get more info here:

Hope that helps.
