[SIPForum-discussion] server response 503

[Sreeji Gopal]

Normally 503 is send as service not avaliable, but in your case the server is not able to understand your register message, once you send the register message, see if u get a 200 ok with authentication header, if u get that u need to send the encoded/encrypted password string.

I am not seeing that happening, if so u need to check the server config and i feel that ur register message is getting expired so if so check your register message header.

My VoIP phone is registered to Asterisk server, and I turn
power off. After I turn power on, my VoIP successfully re-registers to the
proxy.  When I make the first call to the phone in the system, I get “503”
response.  The following is the response from the server:
 
SIP/2.0
503 Server error 
Via: SIP/2.0/UDP 192.168.7.221:54910;branch=z9hG4bK4219157283;received=192.168.7.221

Does anybody know the reason why the proxy responds with
503?

Jing
