[Freeswitch-users] No response to registration requests with high port numbers?

[David Ponzone]

AFAIK, Meraki does not have a SIP/ALG.
Did you check for any FW or IDS policy that could affect the SIP flows ?
Did you check the logs from the FW/IDS to see if packets are rejected ?

On the FS side, you could try adding:

<variable name="sip-force-contact" value="NDLB-connectile-dysfunction"/>
or
<variable name="sip-force-contact" value="NDLB-connectile-dysfunction-2.0"/>

in the user account.
