[Serusers] SER talks SIP to Jabber Server

I'm having a problem putting jabber gateway to work. I'm using SER 0.8.12 and microsoft messenger 4.7 as a SIP client and PSI as a Jabber client. I had configured the jabber gateway in ser.cfg and i can talk between the to clients (at least for a while). I'm using user1 as both SIP client and jabber client, and user2 as a jabber client only. So the SIP address for the user1 is sip:user1@sipserver.sipdomain. user1 also have an jabber account user1(a)jabberserver.jabberdomain. user2 as an jabber account user2(a)jabberserver.jabberdomain. I start to talk from user1 (microsoft messenger logged in SIP server) to user2 (PSI logged in jabber server) and it works just fine. If i continue to talk in this direction i have no problems. When i start to talk from user2 (PSI logged in jabber server) to user1 (microsoft messenger logged in SIP server) i have no problems either. The problem appears when i want to talk again from user1 to user2... that is, when i receive the first response from user2 -> user1 it blocks the way user1 -> user2. I've put a sniffer to find out why this appened, and appears that after user2 responds, all the events (Ex: INFO for Keyboard Activity) or messages from user1->user2 are SIP to jabber server. It seams that SER is not using the jabber gateway. Can anyone help me please... Délio Guerra IT - Instituto de Telecomunicações Universidade de Aveiro - Portugal
