Hi, I just finished a freeswitch server that act as E1 gateway for PBX system. I noticed that all the call from the gateway use PCMU codec before transcoded to G729 in my main SIP server. My current situation is as following : [PBX] --- E1 ---> [Gateway] --- SIP/PCMU ---> [SIP Server] --- G729 ---> [ITSP] What I intended to do is as following : [PBX] --- E1 ---> [Gateway] --- SIP/G729 ---> [SIP Server] --- G729 ---> [ITSP] Is there anyway to send the media from E1 gateway as G729 instead of PCMU? I need to preserve bandwidth for future expansion. Regards, William
Hello William, E1 doesn't work with G.729, it is intrinsically PCM. Unless of course it is non-structured and it is used as an IP link... David On Thu, Feb 7, 2013 at 11:37 AM, William Alianto <william@xofap.com> wrote:

E1 uses G711... I'm assuming by saying that FS is acting as the gateway you're using something like mod_freetdm? If so FS can transcode so that it uses G729 for the SIP side of the bridge. Look at the commercial mod_com_g729 (licenses available for $10/channel on www.freeswitch.org). http://wiki.freeswitch.org/wiki/Mod_com_g729 You just need to have that loaded instead of mod_g729, and tweak your codec preferences accordingly. http://wiki.freeswitch.org/wiki/Codec_Negotiation -Steve On 7 February 2013 10:37, William Alianto <william@xofap.com> wrote:

Hi Steve, I actually has installed a transcoding card along with the E1 card. I was hoping to do something like media proxy at the gateway. Is that possible? Regards, William On 07/02/2013 19:10, Steven Ayre wrote:
