invalid OPTION ping

[Johan1234]

It seems that the OPTIONS method is corrupted.
According to RFC the OPTIONS should be sent from IP Office LAN address to the ITSP proxy address.
In the trace below you can see both FROM and TO field are the same.

Even better: When check OOS is turned off, OPTIONS are still being sent.

Anyone has an explanation for this ??

Sent message is:

I think I had an ASA one time that was fixing up SIP and doing something similar.

 

[holdmusic34]

You mean SIP ALG packet inspection? (turn it off)

Dulce et decorum pro Avaya mori

 

[Johan1234]

No, the trace is from IP Office output. So it's sends wrong initial messages, causing trunk to go busy-out.

Are you sure the trunk is set up correctly? It's hard to answer without more detail on the setup and address scheme etc

 

[Johan1234]

Ofcoarse it is

ITSP Domain name = IP Address of LAN2 (to determine FROM host part)

ITSP Proxy address = 62.140.159.249 (dial peer on CPE that passes through to SBC)

No network topology, no STUN.

It's even reproducable when upgrading from 9.0.2.0 to 9.0.3.0
9.0.2 does not send OPTIONS, after upgrade to 9.0.3+ it does, even when Check OOS is unchecked.

ITSP Domain name = IP Address of LAN2 (to determine FROM host part)

No, this isn't correct, this would typically be the providers address i.e SIPS.NTE.LTD.COM not the systems own LAN2 address

 

[Johan1234]

We don't use DNS, and want the IP address to be the host part of the FROM field.
It's a closed environment, not over public internet.

So then put the IP address of the other device forming the SIP connection, the "From" will come automatically from the interface it leaves over

 

[amriddle01]

I have linked several systems/devices to an IP Office using SIP trunks, never had it fail

 

[Johan1234]

indeed, once i put the trunk IP address in ITSP doamain AND proxy, it worked

Still no good. Now OPTIONS goes well, but FROM field is corrupted.
I keep thinking it's a firmware issue.
