Using SIP with Nokia N900 over O2 Germany
Hello,
i am currently trying to use the SIP Service of my German provider Unitymedia via the Nokia N900. It works very well over Wlan but doesn't work at all over 3G from O2 Germany. Are there any tools or aps I can use to improve the build-in SIP Service? I've already tried a lot of configurations. With Wlan it works with the following: Public Address: nXXXXXX_X@ssl2.telefon.unitymedia.de User: nXXXXXX_X Transport: Auto Proxy: None Port: 5061 Discover public addresses: Yes Loose routing: No Keep-alive mechanism Auto Keep-alive period Auto Stun: No Stun server available Would be very nice if someone could help me.

I have SIP working via EPlus (Simyo) and Sipgate. To make it work I had to disable the G729 Codec by modifying part of the /etc/stream-engine/gstcodecs.conf to:
Code:
[audio/G729] People I am speaking to are sometimes complaining about bad quality, it depends on the network coverage, 3G minimum. |
Re: Using SIP with Nokia N900 over O2 Germany
Thanks for the reply, but that doesn't have any effect on the connection. The N900 doesn't reach to connect with the SIP Service. Error is: "Network error". Is there a log file, which gives me further details on connection errors?
For the S60 3rd Edition Phones it works with the following configuration: Service profile: IETF Public address: h1xxxxxxx_x@ssl2.telefon.unitymedia.de Use compression: No Use security mechanism: No Proxyserver Proxyserver-Address: sip:ssl2.telefon.unitymedia.de Region: none User Name: h1xxxxxxx_x Loose Routing: Yes Transport: Auto Port: 5060 Registrationserver Registrationserver-Address: sip:ssl2.telefon.unitymedia.de Region: Realm User Name: h1xxxxxxx_x Transport: UDP Port: 5060 Is there a way to put this config into the N900? Maybe via a config file which allows advanced sip configuration. Greets Vinc |

sorry, no idea.
I just used my sipgate account data and it worked well. Maybe you could try registering a sipgate account (free) for troubleshooting? |

Could also be your mobile Internet provider has blocked port 5060 (VoIP) on the network?

You could try to sniff the traffic with tcpdump or wireshark on your n900. Sniff it via wlan and than via 3G and look to the difference. With my german O2 and Sipgate it works well, i have 0815 Einstellungen.
