Hello,

My client's VoIP-network is a very simple one with SER. But he has an
Ericsson MD Evolution XL PBX and he wish to make PSTN calls using
SIP-phone. The MD Evolution is an IP-PBX but it uses a proprietary
protocol and is compatible only with H.323 numeric phones... Does anyone
knows if this PBX is SIP compatible ?
If this PBX doesn't work with SIP, could I use a PSTN-SIP gateway like
Asterisk ?

Thanks in advance

Gwen
