Sip.conf Conflicts

I seem to have a mutually exclusive section of code in my vanilla Asterisk sip.conf (real info not shown):

Quote:

externip=my.ip.address fromdomain=my.domain localnet=192.168.0.0/255.255.255.0 qualify=yes

When the code is in place I can reach my remote ATA extensions over in Poland but my Sipgate numbers, although showing registered, fail to connect.

And vice-versa when the code is removed.

Any ideas, please? Is there, for example, an alternative way to get the remote extensions to work with different code?

Many thanks indeed!

Andy

Hi The problem will be with your nat=yes/no settings.

Ian

Thanks for taking the time to reply Ian.

Have you got a few minutes to be specific. Nat is something I struggle with at the best of times!

Nat settings for the remote extensions or Sipgate or both?

Andy

Hi

Need to know the network topology realy

Is * behind a nat router ? and are the sets in poland on a vpn or behind nat as well

aslo what dothe sets sip.conf entries look like and what do the sipgate ones look like

Ian

Nat is present at both ends. Poland has Handytone 386s.

The relevant parts of sip.conf are:

Code:

[general] port = 5061 bindport=5061 bindaddr=192.168.0.45       tcpenable=yes tcpbindaddr=my.ip.address:5061 externip=my.ip.address fromdomain=my.domain localnet=192.168.0.0/255.255.255.0 qualify=yes nat=yes language=en context = default register => username:password@sipgate.co.uk/username ; ; codecs disallow=all allow=ulaw allow=alaw [2208] ; Polish ATA386 type=friend auth=md5 username=2208 secret=password callerid="****" <2208> host=dynamic nat=no qualify=yes insecure=very canreinvite=no disallow=all allow=ulaw ;allow=gsm allow=alaw [sipgate] type=peer username=sipgate fromuser=sipgate secret=password context=default host=sipgate.co.uk fromdomain=sipgate.co.uk insecure=very caninvite=no canreinvite=no nat=no disallow=all allow=ulaw allow=alaw [inbound-sipgate] ; type=peer context=sipgate-in host=sipgate.co.uk fromdomain=sipgate.co.uk

Many thanks for looking.

(Would iTMS mean anything to you )

Changing Nat to Yes from No does not reslove the issue, sadly.

I have isolated the troublesome code to just one line:

Code:

externip=my.ip.address

With the line disabled the remote Polish extension shows as Unreachable. With the line enabled the Sipgate call is rejected.
This is so whether Nat is set to Yes or No.

The TeleMarketing s/w?

I am beginning to suspect that the problem lies elsewhere.

When the bindaddress is set to 192.168.0.45 (the local * machine) the remote extensions work but not the Sipgate ones.

When set to 0.0.0.0 the Sipgate extensions work but not the remote ones.

Is there a way to have multiple Bind Addresses?

Hi

How many interfaces have you ?

and are you port forwardming or is it in the dmz ?

Ian

Hi

Not sure I fully understand your question. * is on a box with 2 IP addresses but only uses one of them.

I am port forwarding to that box. Would it help to put it in the DMZ?

Andy

Hi

Are they both internal IP addresses ?

I also see you have set sip to port 5061 any reason for this ?

Ian

Yes they are both internal IP addresses.

I am using 5061 as there is another PBX on the network listening on 5060 (a Fritzbox).

Would moving Ports around help?
