Nokia E71

Summary: While not as buggy as N95 it is nowhere near as troublefree as the old faithful E65.

Introduction

The phone is a Symbian based business oriented qwerty brick with 2/2.5/2.75/3G and WiFi?. Detailed specs can be found on gsmarena.com.

Asterisk Configuration

The phone will use whatever asterisk will give it as a media address in the SIP dialogue (proxy setting no longer overrides this the way it did in the early Symbian VOIP like NokiaE65). In cases where Asterisk is multihomed this means that all relevant asterisk IP addresses need to be allowed in the iptables rules (if any) and routed correctly.

The configuration of the phone is as follows:

• Create a set of SIP settings for Asterisk
  • The type of profile should be IETF
  • Set the default access point to your WiFi? network
  • Set the username to a full user@realm notation - example e71@mobile.sigsegv.cx
  • Compression is off
  • Registration is always on (required to call the phone back).
  • Security is off
  • Set the registrar server to your asterisk server
  • Set the proxy server to your asterisk server (optional)
• Configure Asterisk sip.conf section

• Create a set of suitable connection profiles by converting found WiFi? sites into a profile or using the profile editor under Settings/Connection/Internet Telephony
• Set the Wireless discovery to a reasonable interval (5 min is usually OK) under Settings/Connection/WiFi
• The phone should now register and work.
