<div dir="ltr"><div><div><div><div><div><div>hello everybody,<br><br></div>i want to configure a sip trunk between a cisco router and my system which has asterisk. this is my scenario:<br><br></div>Freepbx-----my system-----cisco-router----Freepbx<br><br></div>my
system acts like a router. in cisco, if i set just one codec in
dial-peers, every thing is ok and i can make a call. but if i set
different codecs in a voice class codec and assign it to dial-peers, i
can make call but call is terminated.<br></div>i trace all debug messages in cisco and think it is happened when receiving call has a codec which differs with first codec priority in cisco router because my cisco router can not transcode these codecs to each other. am i right or misunderstand?? if it is true, how can i enable transcoding on my cisco router? i have a 2800 router.<br><br></div>any comments ot hints are really appreciated.<br></div>SAM<br></div>
