Hi,
I am hoping someone can help me with a problem I am having.
I am trying to setup a connection from an Elastix 2 server to a Siemens isdx
PBX. The setup is as follows
Elastix 2
*sip trunk*
Cisco 2621XM router with 2 E1 voice interfaces
*QSIG*
Westell IQ2000 protocol convertor
*DPNSS*
Siemens ISDX
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.
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?
Here is the setup I have on Elastix and the Cisco router
