No Audio

1. Brekeke Product Name and version: Brekeke SIP Server , Version 2.1.6.6 Pro

2. Java version: 1.5.0_14

3. OS type and the version: Windows 2003 Std

4. UA (phone), gateway or other hardware/software involved: Grandstream HT-486

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html : 9

6. Your problem: Sometimes there is no audio during call, sometimes does. It depends which SIP termination is used. No Firewall present.

How about local call in the same LAN?
Are you using Brekeke PBX?

From/To UA's at the same LAN, audio is fine. Yes, Brekeke PBX Pro version 2.1.6.6

how about set RTP relay on under that user with problem.

Already activated.

Since the problem doesn't happen in the same LAN,
the cause of the problem will be the SIP termination side..

Does the problem happen in the certain SIP termination?
Which service is it?

We operate our own ITSP. The things is: calls that go by "A" terminator are fine. Others that go by "B" termination have no audio.

Hi,

What do you mean by A and B?

Different networks.

Well, without you telling us anything about those different networks and what about them is different i'm afraid we don't have enough information to help you.

Does no-audio happen in both ways? or one-way?
Is there enough network bandwidth and stability in the termination?
