cisco vs d4-e&m wink

Hi all.

I'm trying to find (perfect) match between Cisco and other equipments regarding analog trunks.

EG: is d4-e&m wink matching with e&m-immediate-start ?

is there any list with these?

thanks you for your reply.

Re: cisco vs d4-e&m wink

Cisco routers support these three types of E&M Signaling:

Wink-start (FGB)Notifies the remote side that it can send the DNIS information.

Wink-start with wink-acknowledge or double-wink (FGD)A second wink that is sent to acknowledge the receipt of the DNIS information.

Immediate startDoes not send any winks
