Hi,

I am having an issue when setting up a SIP trunk in to Lync.

1. Mediation pool is set as TLS 5067-5067 and TCP is 5060-5060

2. PSTN gateway has 88.215.61.201 as signalling gateway and 88.215.61.202 as alternative media. with Lycn set to use all avalibe IP address.

3. Trunk is set to listen on port 5060 protocol TCP and associated mediaserver port as 5060.

Now all incoming calls are working and I can use both Conferencing and direct dial to an assigned number. However all out bound alls are failing with a "call not connected or ended" error

A snoop trace shows

TL_INFO(TF_PROTOCOL) [1]1E2C.2748::02/06/2014-09:21:30.560.001052d2 (SIPStack,SIPAdminLog::ProtocolRecord::Flush:ProtocolRecord.cpp(196))[726616948] $$begin_record

$$end_record

The Line that confuses me is

Peer: IAH-Lync.iah.ac.uk:5070

why is it looking to port 5070? why not 5060 as it is configured to?

In another log entry I see

ACK sip: +441483123456@88.215.61.201:5070;user=phone;maddr=IAH-Lync.iah.ac.uk SIP/2.0
Start-Line: ACK sip:+441483123456@88.215.61.201:5070;user=phone;maddr=IAH-Lync.iah.ac.uk SIP/2.0

Open in new window


again why port 5070 and not 5060 ?

I am sure this is causing the issue but I can see were in the config it is picking up this port number.

Also saw this error

"27591525Incoming session is rejected because Mediation Server thinks its network interface is down.NULL"

One thing I have done is change the IP address of the frountend/media server. every thing else is fine but not sure if there is any thing I need to do in the topology to clear out the old IP record or if this might be affecting it.

Thanks for any help.

Resolved.

Had to go on to the front end server and disable and re-enable the mediator server publishing and re running the setup program each time. After that it is fine
