Unity - VPIM, cannot deliver

I'm testing the VPIM communication with the 3rd party system(Callexpress) and have a delivery issue.

1. Unity and Callexpress both systems are on the same AD domain as name

- create two DNS zones that and and register the A and MX record. unity into and Callexpress to

2. Unity(4.0.4sr1)

- primary location, dialID=1111, SMTP

- delivery location, dialID=2222, SMTP

- subscriber ext=5001

3. Exchange VC

- VPIM transport

- recipient

4. Callexpress

- primary location, dialID=2222, SMTP

- delivery location, dialID=1111, SMTP

- subscriber ext=2002

5. if I send a message from Unity to callexpress, fails the delivery with showing the recipient as

6. if I sending from callexpress, success the delivery with format,

Q} why the Unity send the SMTP doamin format as instead of or please advide to resolve the issue.

Thanks in advance,

Re: Unity - VPIM, cannot deliver

it was DNS name issue. copied the callexpress name from dynamically learned via the AD into zone's A and MX record.

Re: Unity - VPIM, cannot deliver

my previous resolution was wrong. it was my mistake by coincidence. the problem was SMTP domain in the exchange default policy. since remove it I can successfully able to sending from Unity to Callexpress.

- recipient,

The SMTP domain described is the production environment. is there any way to send from Untiy to Callexpress with keep the which Callexpress's local domain?
