[Asterisk-Users] sip registration fails

[Alberto Martínez]

Hello,

I am trying to register in asterisk with a softphone (x-lite) and I am
getting the following message:

Jan 19 13:27:01 NOTICE[3359]: chan_sip.c:7531 handle_request: Registration from 'tito <sip:tito at 192.168.1.2>' failed for '192.168.1.5'

In the sip.conf file I have included the following. Does I need to
include another change to allow the user to register?

[phone1]
type=friend
host=dynamic
defaultip=192.168.1.5
username=tito
secret=tito
dtmfmode=rfc2833
mailbox=1000
context=sip
callerid="Tito" <2124>

I get the following message too and I don't know what does that means:

Jan 19 13:26:41 WARNING[3343]: chan_sip.c:685 retrans_pkt: Maximum retries exceeded on call 5d3ad2484ea1cacc4e77a5252198cfc7 at 192.168.1.2 for seqno 102 (Non-critical Request)
