Call from CMS to ISDN Gateway 8231 fails - local SIP teardown with reason 32

Hi all,

 

I'm having some issues getting a call 384k bonding from CMS out via a Cisco 8231 gateway the current setup is;

 

CMS -> Expressway -> gateway.

 

I have proved the call a H323 registered endpoint on the Expressway - unfortunately I haven't been able to test a SIP registered endpoint at the moment. But when I attempt a call from a CMS space because of the delay from the gateway the CMS send a SIP cancel 40 seconds after the invite which drops the call;

 

2021-06-22 15:44:02.603 Info call 25: ending; local SIP teardown with reason 32 (timeout - provisional responses) - not connected after 0:40

 

I've been checking the documentation to see if this is a value I can adjust but my searches so far have been fruitless.

 

Can anyone offer some advise please?

 

Software versions;

CMS 3.2

Expressway 14.0

GW 2.2

 

Many thanks,
