Hello:

I'm newbie in asterisk, please help me.

My context is as follows:

192.168.4.2 --> Asterisk 11.13.1 complied from source

192.168.4.4 --> Yeastar NeoGate TG100 GSM gateway

When I call from a GSM cell phone, my TG100 GSM gateway answers and
dials extension 7777 (configured as a hotline on TG100) to asterisk
server, but asterisk server sends me "SIP/2.0 401 Unauthorized"
response, I think it's a matter of contexts but I don't find the
problem.

Attached are sip.conf, extensions.conf and debug from 192.168.4.4
(TG100 GSM gateway).

Thanks in advance.


Hello:

I solved my issue by changing type=friend with type=peer in
[555555555] section, afterwards, googling I've found this article that
explain me why:

Re: type=friend is bad for you

Another little known fact about the difference between peer and friend:
Friend will challenge INVITEs. When making outbound calls from a
registered phone/peer another challenge will be issued.

This means type=friend requires second INVITE with authentication
credentials, while peer will accept INVITE without challenge.

In other words type=friend does not care about the phone registration
status and always tries to authenticate as if the phone never
registered.
