[Asterisk-Users] Re: Problems with incoming calls on a E1 ISDN PRI

[Roberto Reiner Uhry]

Hi,

More information!

Look for the last line, this occurs when I receive a phone call from
my zaptel information.

Apr 19 20:08:21 DEBUG[4878]: Set channel Zap/31-1 to read format gsm
Apr 19 20:08:21 DEBUG[4878]: Set channel SIP/6633-115a to write format gsm
Apr 19 20:08:21 DEBUG[4878]: Set channel Zap/31-1 to write format slin
Apr 19 20:08:21 DEBUG[4878]: Set channel SIP/6633-115a to read format slin
Apr 19 20:08:21 DEBUG[4878]: Ooh, format changed from unknown to gsm

On SJPhone shows a message with PCMA
Does anybody have more information?

Tkz,
Reiner
