[Asterisk-Users] Problems using SIPURA and MFC/R2

[Flávio Eduardo de Andrade]

We are using MFC/R2 driver successfully in at least three places in Brazil. 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:

 

Linux [root at asterisk src]# uname -a

Linux asterisk.karsten 2.6.9-5.ELsmp #1 SMP Wed Jan 5 19:30:39 EST 2005 i686 i686 i386 GNU/Linux

 

I did not found significant differences on the sip negotiation between Sipura and Xlite. The only one is SIPURA offer an NSE CODEC. On the reply this codec is not negotiated, it uses only g711u and telephony-event. 

 

Any help would be appreciated.
