[SIPForum-discussion] FW: Alcatel Omni Office Integration

That could be several reasons. Probably, you need to check;
1. Type of codec both ends are using
2. Ensure media IP is allowed (if it is used or there is a firewall)
 
hope it helps.

Subject: [SIPForum-discussion] Alcatel Omni Office Integration

Hi Guys,

I am trying to integrate a Splicecom 5100 Callserver with an Alcatel Omni PBX
over SIP.

The SIP trunks are configured on both ends to register using IP addresses and
no username or password for registration. All of this works fine.

When the Splicecom makes a call to Alcatel, it rings normally and when picked
up, theres a clear audio path for conversation.

However, when the Alcatel rings the Splicecom. it rings as well, but when
picked up, theres no audio path and nothing can be heard. In some cases, it
hangs up after picking.

The two pbx are configured to communicate over a VPN link. The Splicecom has
an IP address of 192.168.110.50 and is connected to router with 192.168.110.1
as the gateway.  On the other end, the Alcatel has an IP address of
192.168.90.2 and is connected to a router with an IP address of
192.168.130.1. Theres some form of NATTing going on at the Alcatel end.

Does anyone have any ideas what could be wrong?

Cheers

Segun
