Hi,
Help me with Answering below questions,
1. When you make a Peer to Peer call using the LYNC Client, are you getting the toast pop up in the other end?
2. If it doesn't ring at all, what's the error message that you get in the LYNC Client
Thamara.

sorry for my English
1-Yes there is a popup window, if you pick up "the phone" , you can talk
2-the user is unavailable or offline (in reality user is available)

Hi,
according to this log file, i see that the other end rings (180 Message) and after some time it disconnects due to time out.
according to this log file, the call should get connected (given that other party answer the call in time). and you should be able to have a conversation. What's actually happening there??
Thamara.
Thursday, September 29, 2011 4:59 PM -
I have a test about it.
I find that if you do not deploy UM and do not set call forwarding and the callee's pc desktop is not active, the call will have call will stop ringing after about 5 seconds.
If the callee's pc desktop is ative(as the mouse is moving, or input), the ringing will be last more times.
Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread.- Proposed as answer by Sean_Xiao Wednesday, October 12, 2011 2:06 AM

Hi,

Thamara.
Friday, September 30, 2011 10:03 AM -
yes and yes, after 5 sec call reject
client LYNC status "Available" (green ico)
Friday, September 30, 2011 10:10 AM -
HI,
1. Is this condition happens to only one User or all the LYNC users having it? (Try running peer to peer calls with several users)
2. if the call get answered within 5 sec window, will the call last till any of the party terminate it
Thamara.

hi,
Every thing looks fine.. you have Session progress message and ringing message. But i need to ask you one more thing. Is there a situation where the same user logged in from 2 end points? may be from a LYNC Client and a IP Phone with the same login.
I suspect it due to this
ms-diagnostics: 13004;reason="Request was proxied to one or more registered endpoints";source="Lync01.co.FIRMA.com";Count="1";appName="InboundRouting"
And i ask you is there any IP Phones involved is due to this

no clue what's going on there.. Every thing seems ok.. If there's no multiple logins with the same sign in address...
by any chance have you restart the system and try?
Thamara.

Hello Tamara, I am having a disconnection issue with external calls only. When calling to PSTN, using Lync/Audiocodes, the calls during is 2m30s.
I got some traces from server and client, with snooper and wireshark, and I see a CANCEL.
Any idea?
Thanks in advance.Wednesday, April 3, 2013 2:45 PM -
from which side that you get the CANCEL request from? is it from the PSTN/Audiocodes side or the mediation server side?

Lync send cancel to the gateway.Wednesday, April 3, 2013 3:13 PM

have you try disabling refer support in Voice routes>Trunks? if it's enabled, make sure that it's the same with the Gateway. is the connectivity is over TLS or TCP? if it's TLS try with TCP.
