[mkumar at mantragroup.com]

Hi All,

I installed Asterisk and trying to configure Vonage with it. After getting
authenticated when I try to call to a number I get the following errors

First I get

Sip read:
SIP/2.0 407 Proxy Authentication Required

CSeq: 104 INVITE
Proxy-Authenticate: Digest realm="216.115.20.41", domain="sip:216.115.20.41",
nonce="365527150", algorithm=MD5

Content-Length: 0

Please help me and let me know my mistake.

Thanks,
