IP Office 500 - From SIP header shows wrong IP Address

[zanewoodfield]

I have an issue with a provider change over. The system is working fine for inbound calls, but our provider is trying to turn on source based routing of SIP at their end, but because the AVAYA presents the wrong IP address in the SIP FROM header, the outbound call breaks.

I have tried modifying ARS, short codes, LAN2 network topology firewall settings all to no avail. Does anyone know how I can get the correct IP address (the LAN2 address of the PBX) to show in the SIP FROM header?

See trace below:

Caller id and contact are fine but from header shows the ISTP Proxy address as the from as well as the TO.

Haven't tried that since v4 but in ars you set it as n"@you.ip" but in v7 works different.

I have tried changing the ARS settings to my public ip on the IP Office but this did not help... I am thinking it is a limitation on the IP Office - I notice V7 has quite a lot of changes in the SIP URI trunking area..

Tried to fill just one of the ITSP's "ITSP Proxy Address" or "ITSP Domain Name" don't use both. Also play with "Send caller ID"

either downgrade to v6 and use ars to send your ip or tell your provider that source ip should be source ip and not what is in the packet. we use trusted source ip for a lot of our clients too but we look at the actual IP the packet is received from. in your case I could easily put your public ip in my ARS table and make calls via your provider on your account, not very secure and sort of defeats the whole purpose.

Try changing the "ISTP Proxy address" to the IP address of LAN2.

Will give that a go tomorrow. Cheers.
