<div dir="ltr">I have the following scenario : <br><br><br>Pstn Number(1234567) <-----------> Asterisk GW <----------------> Openser | <-------------->11803 <br> |<br>
|<br> | <--------------> 11801<br>
<br>Firstly extension 11803 will call the pstn number and this works fine without no problem , after that 11803 will put 1234567 on hold and will call 11801 , then 11803 will transfer 1234567 to 11801 (<---- the problem now started ), what is happening now is that both 123456 and 11801 will be on hold with 11803 after the transfer is done <br>
<br>I've traced the full dialog between the three extensions and found an interesting part , which a NOTIFY message came from asterisk and contains this sentence : SIP/2.0 481 Call leg/transaction does not exist<br>
