[Asterisk-Users] Grandstream HT286 1.0.4.63 & Meetme

[Vladyslav]

Good day!
Have a weird problem with HT-286 and Conference room. I use Asterisk
CVS-HEAD-06/04/04.

Here it is:
 When HT-286 get into the conference room first and nobody in that room
everything seems ok (with any codec HT286 allowed), but when HT-286 get
into conference room when somebody already there, have got different HT
behavior:
 1. When HT use GSM codec => it connects to conference room, but hear
nothing (just dead ear). 
 2. When HT use G729 codec => it gets busy signal and I could see such
output on asterisk console (
Jul  1 07:26:14 WARNING[737298]: chan_sip.c:1611 sip_write: Asked to
transmit frame type 4, while native formats is 256 (read/write = 4/256)
Jul  1 07:26:14 WARNING[737298]: app_meetme.c:896 conf_run: Unable to
write frame to channel: No child processes
Jul  1 07:26:14 WARNING[737298]: app_meetme.c:896 conf_run: Unable to
write frame to channel: No child processes
)
 3. When HT use G711 (ULAW) => it gets into conference room without any
problem.

Any advise appreciated.
