How to call forward all incoming calls coming in to SP2 to SP1

<< < (2/2)

RonR:
By default, the OBi uses ports 16600-16998 for RTP.  Hopefully, your router has an area where you can set ports to be forwarded.  You would forward the range 16600-16998 to the LAN IP address of your OBi.  The protocol is UDP.

Hello RonR,

I need your attention again. Can not receive call on my phone (Sp1). Also can not hear when i call (and get connected ) from phone (sp1) to sp2 that automatically transfers to my cell unconditionally.

 This is the setting in my router
1. Set the LAN port and IP information.
  Starting Port: 16600
  Ending Port: 16998
  Protocol: UDP
  LAN IP Address:   obi IP address

However, I did not put anything in the following section
 
2. Set the remote port and IP information. (Optional)
  Starting Port:   
  Ending Port:   
  Set Remote IP Address:

I always forward SIP and RTP ports.  I give each ATA its own range of each and then explicitly forward those ranges to the appropriate device (whose IP address is fixed by static DHCP assignment).  I also use a STUN server in each device (stun.ideasip.com).  I have never enabled ICE or used any of the optional parameters.

Some argue that all these steps shouldn't be necessary, but in combination with Tomato firmware in the router, I never have call connection problems nor audio issues of any sort.


In case, you want to know my setting for both, ITSP Profile A & B:-

Name         *   
SignalingProtocol                         SIP   
DTMFMethod                               Auto
X_UseFixedDurationRFC2833DTMF   checked!       
DigitMap (1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|011xx.|xx.|<8835100>xxxxxxxx|8835100xxxxxxxx|(Mipd)|[^*#]@@.)   
STUNEnable   checked         
STUNServer   checked         
X_STUNServerPort   xxxx         
X_ICEEnable       checked            
X_SymmetricRTPEnable     checked         
         

Thanks

RonR:
FWIW, I don't enable:

X_ICEEnable
X_SymmetricRTPEnable

Shammi:
Hello ronR,
Do I have to sign up with services like STUN server (stun.ideasip.com) if I enable
STUNEnable   checked         
STUNServer   checked     

RonR:
No, simply set:

STUNEnable : (checked)
STUNServer : stun.ideasip.com
X_STUNServerPort : (Default checked)
