[Asterisk-Users] Help. New SIP hardphone.

[Boater]

I have an Avaya 4602SW SIP phone.
They just released the SIP firmware for it the other day.

I have it working with my Asterisk, but have a couple issues.

My setup is like this: Avaya 4602 phone at home behind router and Asterisk server is straight on the Internet.

My phone registers with Asterisk and works fine, but after a while when I pick up the handset and dial a number after I get to the last digit it just beeps at me like its out of service or has become unregistered.

I am just guessing that the phone is becoming unconnected from Asterisk b/c in the CLI I see a lot of:

-- Got SIP response 481 "Call Does Not Exist" back from my.home.ip.address

But this doesn’t appear in the CLI until several minutes after the phone is turned on.

When I reset the phone it dials out just fine.

The other thing is this. When I look in my outgoing log on my router which my phone is connected to I see:

192.168.1.52(phone IP) asterisk.public.ip 5060

But when I do “sip show peers” it shows:

Name/username    Host            Dyn Nat ACL Mask             Port     Status

2002/2002        home.ext.ip     D   N       255.255.255.255  1029     Unmonitored

Why does the wireless router at home show it going out 5060, but Asterisk shows it on port 1029?

As well, I also get the following:

Jul 18 02:11:22 WARNING[1133718080]: chan_sip.c:601 retrans_pkt: Maximum retries exceeded on call 5c1eac5d0c94f5056a585f5d7f2e7681 at x.x.x.x for <mailto:5c1eac5d0c94f5056a585f5d7f2e7681 at x.x.x.x for>  seqno 102 (Non-critical Request)

In all, the phone is great, the sound quality is superb, but I don’t want to have to reset it every 30 minutes or so just to use it.

Any help will be well appreciated.
