Hi Andreas,<div><br></div><div>Call signalling all works fine right through out from NITB to LCR and out on SIP. how ever im getting some strange media behaviour.</div><div><br></div><div>My setup is,</div><div><br></div><div>
[MS]---[nano.BTS]---[NITB/LCR]----[SIP Softswitch]</div><div><br></div><div>LCR is setup to bridge two interfaces, so what ever comes from gsm goes to sip and what ever comes from sip goes to gsm.</div><div><br></div><div>
Now a test call from a mobile to mobile, should go all the way to the softswitch and come back.</div><div><br></div><div>All works fine in terms of signalling.</div><div><br></div><div>But in media, LCR seems sending initial SDP to the softswitch as PCMA:8 not gsm FR.</div>
<div><br></div><div>So softswitch expect the media as PCMA and not transcoding.</div><div><br></div><div>Same if the call goes out from softswitch, still no medial as it think incoming media from LCR is on PCMA.</div><div>
<br></div><div>Any idea about this ?</div><div><br></div><div>This is the LCR trace -

Hi Andreas,<div><br></div><div>It was apperently compiled on my debian while i had misdn libs isntalled. Now im trying on a fresh debian from the same set of sources which i got it working and without misdn, it fails to compile gsm.</div>

><br>
</div>yes, this was my intention. gsm and sip interface of lcr will not rely<br>
on misdn anymore. currently i don't support audio transfer via chan_lcr,<br>
so chan_lcr will only work with isdn interfaces. the sip interface<br>
implementation has not much options, so it can only do sipmple<br>
point-to-point sip connections to a gateway or endpoint.<br>
