<div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">Hi,<br>I am hoping someone can help me with a problem I am having.<br>I am trying to setup a connection from an Elastix 2 server to a Siemens isdx PBX. The setup is as follows<br><br>Elastix 2<br> *sip trunk*<br>Cisco 2621XM router with 2 E1 voice interfaces<br> *QSIG*<br>Westell IQ2000 protocol convertor<br> *DPNSS*<br>Siemens ISDX<br><br>So the Elastix box has a SIP trunk to the cisco router which then talks QSIG to the Westell which converts it to DPNSS to talk to the ISDX.<br>I have managed to make a call from a phone on Elastix to a phone on the ISDX but it drops after about 3 seconds, every time. Would anyone have any idea why this is? <br>Here is the setup I have on Elastix and the Cisco router<br><br>Elastix SIP trunk PEER
