Cisco Call Manager 5.1 to Alcatel OXO SIP

We have a cisco call manager in site1 along with an alcatel OXO in site1 which are linked via SIP.

There is also a call manager express in site b linked via a wan.

when someone in siteb calls an extension on site1 on the cisco call managaer and then this person tries to transfer this call to someone on site1 on an alcatel phone which is linked via sip then the call drops.

has anyone seen this problem and what are areas to check ?

HI,

I will begin to look the set up for the transfer call. Perphas the signaling between call manager and alcatel is not understanding the tranfer.

When is droped the transfered call? after the cm in site1 tranfer the call o after the call is established between siteb and alcatel?

hiya,

you get one way communication between siteb and the alcatel.

i think its the alcatel phone can hear the other person but not the other way round.
