one way audio on external SIP softphone
« on: June 06, 2006, 05:25:21 pm »
Hi,

I have SIP softphone on my laptop registered as local extension. But when I call another local extension in house from remote location, I get audio only in one direction (from house to me).

Any hint, any setting that needs to be done ?
Anyone have this working ?

Regards,

Rob.

Rob, the problem seams to be from some Intel based sound cards. In alsamixer, the capture should be set from the MIC and not from other device such as CD or something else. Try to change it in alsamixer and tell me the result.

you can use the command
Code: newbielink:javascript:void(0); [nonactive]
amixer -q set Mic cap

Here is a png wich shows that is wrong to be on the CD, change it on the Mic

Hi,

thanks for info - it will be handy. But my situation is slightly different. I call from one SIP softphone on my laptop to another HW SIP phone in my house through Asterisk-Pluto.....

Regards,

Rob.

G'day

Thats the common NAT issue. Make sure the extention that will be used from a remote site has NAT=yes, and also you will need to open port 10000-20000 through your router to the asterisk box.
