Hi All, Could you please tell me what is meant by 9729 codec in passthrough mode in the class 4 routing case. For example if Originating provider supports g729 and is sending call to FS which recieves and routes the call to termination provider who also supports g729 codec. So is the license required in this case or not? Thanks for your time. Regards--------------Abid SaleemSr. Product ManagerTerminus Technologies

If G729 is at both ends, then no encoding/decoding is required as the raw data can be sent straight through. This is passthrough mode. Because there is no encoding/decoding stage, there is no licence required in this case. -Steve On 2 October 2010 13:44, Abid Saleem <abid_freeswitch@live.com> wrote:

A more appropriate way to say this is no transcoding. Encoding/decoding processes are still done at each endpoints on the device, i.e IP Phone, ATA, and/or computer (with softphone), and a G729 license is still required when the call uses the G729 CoDec (which is mostly paid when one acquired the device with a built-in G729 CoDec). So, to say no encoding/deconding involved and no license required are really misleading and definitely incorrect. BTW, one can also configure his/her FS system with bypass media option to ensure the FS only does the SIP with no media handling. The advantage using this approach is to leave FS alone and free up some of its networking resounrces to handle the media during a call. There is also some disadvantages, i.e. no MOH, etc. ----- don't and stop are the ONLY two 4-letter words considered offensive to men, but not when used together. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/g729-passthrough-mode-tp559419...

Mazilo, I think Steven meant that no transcoding was required at the FS level, which was the point of Abid's question. And the main disadvantage of using bypass media is probably the NAT handling, and the lack of topology hiding.

"I think Steven meant that no transcoding was required at the FS level, which was the point of Abid's question." Yes, to show it's specifically the lack of encoder/decoder that means no license is required and that it's the raw data from the client that's sent straight through in passthrough. Which isn't quite how it works with other codecs where you can attach media bugs etc which you can't do with a passthrough codec. "And the main disadvantage of using bypass media is probably the NAT handling, and the lack of topology hiding." Plus in a lot of cases firewalls may not allow it. Example 1: We have customers -> FS -> gateways. Gateways are reachable by FS but not from customers (due to IP ACL on gateway firewalls). Example 2: We have also have customers -> FS -> gateways. Gateways are on LAN, so reachable from FS but not from customers. In both those cases bypass media wouldn't work, since there's no way for traffic to go between the gateways, but FS can't know that so the call would be setup but with no audio. -Steve On 3 October 2010 21:06, David Ponzone <david.ponzone@ipeva.fr> wrote:
