three places in <st1:country-region w:st="on"><st1:place w:st="on">Brazil</st1:place></st1:country-region>.
I have problem with an Asterisk integrated with MFC/R2 with a Siemens Hicom
300. I can get a good audio quality with Grandstream, Polycom, and X-Lite
softfones, but SIPURAS and Linksys get a garbled audio, something like a
“Darth Vader” voice. We have tried everything in Sipura. The SIPURA
2000 and the Linksys work fine calling a URA menu on the Asterisk and can talk
to each other with excellent audio, only SIPURA->PSTN(HICOM) gets garbled.
When I use X-LITE->PSTN it works fine. The negotiated codecs are ulaw
we’ve forced it in Asterisk and in Sipura. We are using version 0.0.3
pre4 of unicall, The linux version is:<o:p></o:p></span></font></p>
