-bunch of SPA-942
-2x SPA-400 as incominng PSTN line
Main codec used by VoIP provider and my SPA-942 is G726-32 and it’s working fine. Unfortunatelly SPA-400 works only with G711A, G711U and G729.
Soo asterisk have to do stream conversion.
When call is established without transcoding G726<->G726 or G711<->G711 sounds great.
But when call is transcoded by server G726<->G711 sound is choopy and very but quality.
To get situation more complicated, setup is:
sip_peers confinguration in mysql database without “any codec overides”
spa942-spa942 call should be G726 and is working
spa400-spa942 should be ulaw but it’s NOT WORKING and is ulaw-server-G726 (sound chopy)
Asterisk 1.2.19 on the same machine and nearly (1 test peer in file not in database) is working: ulaw-server-G726, sound is good.
Please help me
