A reliable SIP registrar?

[peter@easthope.ca]

Hi,

For the Ekiga client in Debian, the Ekiga SIP registrar always works.  
For other systems the Ekiga registrar can fail.  Mikhail Zabaluev  
comments in https://sourceforge.net/p/sofia-sip/bugs/102/ at 
2009-06-08, "The restriction imposed by the proxy is arbitrary. It 
does not follow any specification or best practice published by IETF 
that I'm aware of."

Diamondcard.us works for any system I use but is paid gateway to the 
PSTN.  Can anyone recommend a SIP registrar for general use beyond 
Debian?

Thanks,                            ... Peter E.
