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.

I'm beginning to think that this high port number thing is a red herring. The router in question is a Meraki and it seems to have trouble allowing more than one SIP client to register with freeswitch (maybe a NAT/ALG issue)- is this some kind of FAQ?

Hi,

Got a problem with a handset that doesn't seem to be registering on our Freeswitch server. The diagnostics from a member of Cisco support said...

"At packet 422 we see the phone "0_4147057716@192.168.40.26" send a registration request to 5.9.36.113:5060 from 175.159.77.82:32060 - We do not see a reply to this from the SIP provider.

We responses to requests from 0_359240637@192.168.40.26 with source port 5060, which suggests to me that the SIP provider is not replying to the high UDP port requests. As the MX is a NAT device, subsequent SIP requests will always have a high UDP port."

I'm not sure where we might configure acceptable ranges of SIP source or if it's something else.

Thanks for any suggestions...

Alex
