Hi !
I have a TDM40B and i try to use it connected to modem for incoming call data transfert.
I have no problem to use it with a phone and a talk communication work fine.
But when we try to use with modem, with most modem, we got data carrier for few seconds and channel hungup.
< [ TYPE: Null Frame (4) SUBCLASS: N/A (3) ] [Zap/4-1] -- Zap/4-1 is ringing << [ TYPE: Null Frame (5) SUBCLASS: N/A (0) ] [Zap/4-1] << [ TYPE: Null Frame (5) SUBCLASS: N/A (0) ] [Zap/4-1] << [ TYPE: Null Frame (5) SUBCLASS: N/A (0) ] [Zap/4-1] << [ TYPE: Null Frame (5) SUBCLASS: N/A (0) ] [Zap/4-1] << [ TYPE: Null Frame (4) SUBCLASS: N/A (4) ] [Zap/4-1] -- Zap/4-1 answered SIP/213.161.193.64-08142788 << [ HANGUP (NULL) ] [Zap/4-1] -- Hungup 'Zap/4-1'
I try to configure channel in different mode, without echo cancellation and seems same problem.
This configuration is working perfectly with HandyTone from GrandStream.
Our zapatel.conf look like this (but i have also test with light configuration) :
signalling=fxo_ls ; try also ks ... group=1 relaxdtmf=yes ; make no difference context=sip echocancel=no faxdetect=no ; make no difference channel => 1-4
All call are incoming call (from PSTN or SIP G711 - ASTERISK - TDM40B - MODEM)
Modem said "no carrier" when answering with ATA. With a fax machine, i think we will get same problem haven't yet test)
Any idea ?
Thanks for help !
