The problem (complete silence, user do not hear anything) occurs when user gets into conference room (via SIP) from Grandstream HT286 and someone already in it.


Tried with different image version for HT286 (,, and with different codecs.

If you do a dump on the wire, what do you see?  What makes you think this is an Asterisk bug as opposed to a grandstream bug?

Hello, is there any interest in this bug anymore?

By: vladuk (vladuk) 2004-10-04 09:27:39

U are right could be a Grandstream bug, but do not know how to prove to Grandsteam that this bug is related to them.
any advices?

Yes, my advice is to look on the wire using ethereal and see if there are or are not packets going to the phone during the silence period.

Right, during silence period there is no packets from * to ATA box at all.
Packets are going only in one direction from ATA box to * only.

What do you see on the screen during that silence period if you're looking at the Asterisk screen?

This is from Asterisk screen:
"Oct  1 11:35:29 WARNING[1114532784]: chan_sip.c:1857 sip_write: Asked to transmit frame type 64, while native formats is 8 (read/write = 64/8)

Thank U so mush, for your assistance.
But when I install everything from scratch on another box it's working now.
So the bug somewhere on my box.
Sorry, for that. I had two boxes with the same problem I thought it could not be just like that....
but when I reinstall => ...
However it's strange what could cause that :(
anyway thanks a lot again.

Okay I'll just suspend it then.  Maybe you had an old version of software or something.
