[Serusers] RE: no voice - sr-users

29 Dec 2004

Hi,

I am calling from Line1 to Line2 on the same box.

Still, I cannot hear any voice from each other. I have captured the SIP
packets, I can see the SIP Request, ACK, BYE, as well as SIP/SDP
packets. Everything seems to work properly.

I am using STUN also. If I use serctl ping sip_addr the two lines will
response with 200 OK.

So, I don't know what is my problem. Can anyone tell me how to configure
this?

  Hi Thomas,

 Is UA1 and UA2 on the same device ?
 The signalling of the call is done between your SPA-2000 and your SER box,

  but when you pickup the phone, the SER box is out of
the loop.
 So, if you're calling between two different devices, you can check the
 network path between the devices. If you have a firewall that does NAT,

  then this is where you should start.
 If you try to call from Line1 to Line2 in the same box, your settings
 would be the first place to start.
 Ie, what is the contact address of your UA's ?
 You can check this with the "serctl ul show".
 The field you should look at is the "Contact" field.

 Hope this gets you going...

 Thank you.
