What service provider are you using?


Many 'codecs' are supported under SIP. But the SIP specification mandates all SIP connections must support type 0 uLaw to be able to call itself SIP. It sounds like your company is not providing type 0.

I'm in Argentina and ther service provider is VONTEL (www.vontel.com.ar). There you can download a softphone. I use other softphone and a Sipura SPA-2000, and works fine.


I think that incoming calls are made with a code like 711 or 729.. (I don't know really much).


Thanks for your help!
