[asterisk-users] OT (semi) E60 problem

[Martin Joseph]

Hello again gurus.

I have been using Asterisk with great results going on a couple of  
years now.

My primary box is running asterisk 1.42 built from a tar ball on Mac  
OSX 10.4.9.

I have a very odd issue that I cannot seem to nail down, which is  
related to my Nokia E60 SIP phone.

I use the E60 with very good results (latest firmware) from several  
locations.

Basically it works fine from everywhere EXCEPT when it's on the same  
LAN as my asterisk box.

The SIP config. that I have setup for the LAN connection refers to my  
asterisk box by it's local IP (ie 192.168.1.101).  The external  
configs refer to the asterisk box by it's name (ie sip.domain.com).

It seems like this has something to do with the authentication  
realm?  If I  create a new config on the phone using the LAN address,  
it works, but then when I leave the LAN, it appears to register,  but  
issues a "connection error" when I try to place calls.

To get it working again from outside the LAN,  I can change the realm  
parameter in SIP.conf, and then reload and then change it AGAIN back  
to it's original value and reload, the phone then works fine.   At  
that point, the LAN based config won't work anymore and will give me  
a "connection error".

Any thoughts on this?  Ideas on how to troubleshoot further or work  
around it would be great.

Thanks,
Marty
