Are there any specific reasons why you do not want to use G711 in the sip client, which is "working fine"? (Nota bene: there are some more codecs supported by asterisk, some of which may be also supported by your sip phone) Your E1 trunk obviously is G711-only - this is to be expected, because the G711 wave samples are those which go over the wire (as time-division multiplexed bitstream). Together with the information from http://www.voip-info.org/wiki-Asterisk+G.729+Licensing namely ** G.729 requires a license per channel unless it is used ** in pass-thru mode. which exactly matches your setup (by the way that was the first google match for "g729 asterisk") we can guess that you did not buy the license which would be necessary for asterisk to transcode G729/G711. > [sip_phone]------[asterisk]-----E1----[Avaya]----[analog_phone] > > Asterisk sip client configure with g.711 alaw/ulaw > Avaya phone client configure g.711 alaw/ulaw > > suggest how do it implement g.729 on this case what change i have to > done on both part Avaya / E1 stays as is, sip client stays as is, your credit card data is transferred to digium, and their license goes into the appropriate file on your asterisk machine hard drive. Others may have real world experience with those steps, but that is what I read on this mailing list.
