Nortel i2001 over Asterisk

[lordluis2000]

Hi someone knows why I can not uses 2 nortel's phone in Asterisk? using unistim.conf and UNIStim protocol

The first one works good
The second does the register, but when I make a call I cannot hear the other extension and when I place a call to this extension goes direct to mailbox.

Any idea about this?

There is no SIP firmware for Nortel i2000 series phones.

I was running a sniffer in orther to get some differences and I placed a call from a computer with a softphone and WireShark. I got the packages. I saw that with the phone who works the Server and softphone send and receive RTP packages (both directions) and the other case (not working phone) just softphone send RTP packages but Server never answer

Is it possible that iptables has blocked the ip of that phone?

Well I did try changing the IP of phone, changing extensions from one phone to other. But anytime I set two extension 133 and 134 always the mac-address under extension 133 works and the only way extension 134 works is deleting from the unistim.conf the extension 133. On my opinion the server just take RTP packages from the first mac-address in the config file and the second just ignore.
Probably I missing something. But not idea what and where.
