SPA303 2-Lines Config

Unanswered Question

User Badges:


I have a SPA303, I was using it with just one phone line but now I need to add a second one, so I configure it, here how I did it, from the http://IP/admin/advanced WUI I configure the EXT1 and EXT 2 like this:


  • Proxy and Registration:

Proxy: sip.ovh.fr

  • Subscriber Information:

Display Name: Name1

User ID: PhoneNumber

Password: PASSWORD

Use Auth ID: YES

Auth ID: PhoneNumber


  • Proxy and Registration:

Proxy: sip.ovh.co.uk

  • Subscriber Information:

Display Name: Name2

User ID: PhoneNumber2

Password: PASSWORD

Use Auth ID: YES

Auth ID: PhoneNumber2

I submit the config, my SPA303 restart and then where I find a problem, actually in the LCD screen only the phone number configured in the EXT1 is showen for all of the 3 lines!!

When I look at the Status menu in the phone I find that my EXTs are well configured!!

I tried to disable the EXT1 and leave the EXT2 enable, after the reboot I have nothing showne on the screen!!

Thx for your help

Hey Luis,
Thx for finding time to answer me

I think that my Netowok Toplogy have nothing to do with the problem described in my above message, I think that this is a hardware or software problem, I already upgrade my SPA303 to the latest Frimware version..

But I'll answer you any way because my topology cause an other problem, actually I have a server host a GW powered by Endian FW wich is connected to an SDSL(RED) & my LAN(Green), my LAN use the Star Topology.

My second problem is with the sound, I enabled the port 5060 in my Endian FW so now I can make/receive calls but I can here nothing when I answer that call, need I to open other ports??

The port 5060 is standard SIP protocol command port. But you need another ports for RTP (e.g. audio) channel. The exact port number for RTP is ad-hoc selected from configured range.

The range in question can be configured, read:

You can open only ports from the range instead of all ports.
