<br>
The Sangoma G.729 is a transcoder. You don&#39;t want that for ptime<br>
resolution. Decompressing and recompressing really hurts the quality. FS<br>
will repack the frames to resolve ptime mismatches, although the latency<br>
is better if you can avoid such repacking.<br>

&gt; Hi Steven<br>
&gt;<br>
&gt; Yes we have tried the passthru_ptime_mismatch set to true but that<br>
&gt; didnt solve the purpose. So we decided to try sangoma. Trouble is FS<br>
&gt; uses the sangoma even in case of passthrough. Is there something that<br>
&gt; can be done to use mod_G729 for passthrough and sangoma g729 for ptime<br>
&gt; mismatch ?<br>

&gt;     First have you tried passthru_ptime_mismatch=true yet? It&#39;s not<br>
&gt;     the default used by the passthrough mod_g729 codec.<br>
&gt;<br>
&gt;     Only one module can be loaded at a time to provide a given codec<br>
&gt;     (ie mod_g729 or mod_com_g729 or mod_sangoma_codec). Internally<br>
&gt;     perhaps the sangoma module would avoid licenses, but they would<br>
&gt;     need to clarify. AFAIK mod_com_g729 only uses a license when<br>
&gt;     required, simple 729-729 bridges still use passthrough, but I<br>
&gt;     don&#39;t know how ptime affects that. It&#39;s be easy to test though -<br>
&gt;     load it without any licenses and try a 729-729 call with differing<br>
&gt;     primes and see it the call gets through.<br>

&gt;         Looks like we would need to purchase a G729 license for<br>
&gt;         Freeswitch or use a Sangoma card. Is there some configuration<br>
&gt;         which tells Freeswitch to use the card ( or the software codec<br>
&gt;         ) only in case of a ptime mismatch  so that we could save on<br>
&gt;         the licensing fee only for calls that actually need ptime<br>
&gt;         conversion ?<br>

&gt;                 Hi<br>
&gt;<br>
&gt;                 I am trying to configure FS as a B2BUA which can do<br>
&gt;                 ptime conversions between the ingress and egress leg.<br>
&gt;<br>
&gt;                 The question is, if both legs have G729 as the codec<br>
&gt;                 but ptime 20 on one and 30 on another, would i still<br>
&gt;                 need to get the licensed mod_com_g729 or can it work<br>
&gt;                 with the passthrough mod_g729. I already tried it out,<br>
&gt;                 but it doesnt seem to work.<br>
&gt;<br>
&gt;                 Is there some configuration needed for this ?<br>
