SV: [Asterisk-Users] ZAP/DTMF

[Dmitry Zhukovski]

Hi community!
 
 If somebody is interesting in issues I found then configuration I have described above has strange behaviour ONLY when Asterisk 1 has Sangoma 4 PORTs card. Pairs Digitum/Digitum and Sangoma 2ports/Digitum are OK - DTMF are passed thru E1.
 
  I am going to contact Sangoma.
 
Br,
Dmitry

	Hi all! 

	  I have got strange problem with DTMF. This is my test setup 

	Phone1(#101) --> (*1) -----E1------ (*2) <-- Phone2(#201) 
	*1 handles 1XX numbers 
	*2 same for 2XX 
	*1 and *2 have proper routings so phones can call each other 

	*1 has dial number 103 which answers automatiaclly and get keys and tells their voice equvalent 
	*2 has same functionality on autoresponder #203 

	Test cases: 
	1) Phone2 calls 203 - local (*) - asterisk detects dtms and run in proper way 
	2) Phone2 calls 103 - thru ZAP - works well 
	3) Phone1 calls 103 - local (*) - works well 
	4) Phone1 calls 203 - thru ZAP - DTMF are not detected ! 

	So it works only in one way. Any ideas? 

	Btw - with debug on ZAP channels case 2 gives on asterisk2

	And on asterisk1 

	<< [ TYPE: DTMF (1) SUBCLASS: 1 (49) ] [Zap/1-1] 

	In case 4 ----------> 
	Asterisk1 has

	And NO MESSAGES on asterisk2! 

	Looking forward to get any help!
