#2067 No connection possible to AVM fritz!box with HTC Desire Z (Android 2.2.1)

[Anonymous]

Originally created by: kai.ml...@gmail.com

What steps will reproduce the problem?
1. Create an SIP-Account using a AVM fritz!box 7270
2. Enable the account in CSIPSimple

What is the expected output?
As in the previous version: "Connected"

What do you see instead?
Something like "Connection problem" (can't test it now, but it was not much info)

What version of the product are you using? On what operating system?
I switched back to an older version, which worked fine. The Problem occured on the version which is available via Google Play Store since 19. September 2012. I'm using the pre-installed Android 2.2.1 on a HTC Vision (aka Desire Z). Version-Information of the fritz!box is not available, since I'm unfortunately not officially the network-administrator.

Please provide any additional information below.
Sorry for my bad english ;-9

Can you try to follow instructions that solves problem for this user :
https://code.google.com/p/csipsimple/issues/detail?id=457&can=1&q=fritz

(instructions are there :
https://code.google.com/p/csipsimple/wiki/FAQ#I_receive_calls_twice_/_Registration_is_done_on_the_sip_server_t

Section : "I receive calls twice / Registration is done on the sip server twice"
)
switching on "legacy" mode instead of normal could help if the version of your Fritzbox is buggy and doesn't support the all in one contact rewrite method.

Yes it works now. Thanks!

But isn't the "contact rewrite"-feature the thing which allows the Server to show a name (i.e. "Phone1") instead of the number (i.e. "**611")? This still works too.

Allow contact rewrite changes the call flow.

In fact in SIP the sip client is supposed to register using it's public IP.
The concept of "public IP" here is actually the IP as seen by the SIP server.

The sip stack used in csipsimple (pjsip) tries to autodetect the "public ip".
One of the way to get that is to get the Via header in the first register and to rewrite it in a second register round.
It's a little bit tricky ;)

To show a different display name, in expert mode you can change the SIP ID (AoR) to have something like
"Phone1" <sip:***6111@domain.com>

This display name feature is also known in the interface as "Caller-ID" (as many sip providers use it as caller id).
