Unable to do blind transfers over T1 route

[Kickersport]

I have am using a regular T1 to tie an Avaya IP 500 and a Nortel Meridian 1, when I do a blind transfer the line gets disconnected. To keep the call up I have to ask the receptionist hold the line until the transfer is complete.

yes this is normal when doing a trunk to trunk transfer. you have to wait for it to start ringing before you can complete the transfer.

Yea even when the phone starts to ring if I release the call before it is answered the call gets disconnected.

Then the Nortel sends a call progress message to the IPO while the IPO expects a Connect message if the station starts to ring.

Sounds like the Nortel isn't passing call progress messages back to the IP Office so it has no indication how the call is progressing until it it actually connected

Can you brief me on how to have this implementation done.The have the call progress messages sent between systems

This needs to be done in the Nortel, our expertise is with the IP Office I'm afraid

And we plan tok eep it that way, in a few years the Nortel systems are history like many other systems bought by Avaya.

Nortel is on its way out for sure...

If this is a regular T1 with in-band signaling, there are no progress or connect messages between systems. Call status is determined by the status of transmit and receive bits.

My guess would be that the two ends of the T1 are not administered to match. We would use classic E&M signaling - have made this work between IPO and several other non-Avaya systems.
