[Asterisk-Users] Problems to register with SIP provider

[Lars Fredriksson]

Hi!

I have some problems registering with the Swedish SIP-provider Telia - I
have set it up so I can dial out (and it works almost all the time, not all
number works from Asterisk but I think it might some other problem).
The problem I have is to register it as a peer so I can receive calls.

I don't have an external IP to my Asterisk box - our provider just have one
IP that all who lives here around shares - but the SIP client provided from
Telia works (it's from www.hotsip.com I think)

Here comes some output from the registration process:

--<SNIP>--

<ip-adress> = the IP to the proxy
<my no> = my telephone number (and also my username)

It looks quite strange - Like Digest username above="<my no>@" ans
uri="sip:<ip-adress>"
