Dear Team,

We have one remote site with three phones connected via VPN from main site. the phones are having same configuration as in main site .

we are able to make outgoing calls from these phones both internal and PSTN . but we are unable to reach these phones dialing extension and direct line as well . even the phones are not mutually reachable . please suggest .

Regards

what do you mean by "not reaching"  you mean when you call them from within your organisation they ring, but no voice?

remember RTP is point to point, so make sure you can route to your VPN subnet from any voice subnet in your organisation that needs to call these phones

Do a DNA form CUCM for remote phone scenario 1,2 and 3 Above and attache output here.

For DNA go to CUCM Serviceability Page (<CCMIP/ccmservice> ) and Tools Dialled Number Analyser.

Search for respective phone and do analysis for above scenario, paste output here.

You might have some partition,CSS issue.

Thanks

To verify if this is a firewall problem you should take a packet capture from IP phone and traces from CUCM for a test call to see if all the packets sourced from IP phone and CUCM make it to the other end successfully. If you can open all SIP and UDP traffic between this site and headquarter as a quick test then it can help as well to identify it quickly.

Hi,

I checked the traces and reason of failure that your CUCM isn't able to establish TCP connection to your remote phone (610) at IP 172.21.20.3 port 5060.

See below traces (I  highlighted the important parts in red). You need to check your routing and access control rules

Hi Mohammed,

we have verified with firewall vendor , but they said no issue from firewall .

previously we had one way audio issue . but when I added IP route to the new network from gateway , it has been resolved . other than that what can be the issue in routing part , kindly suggest.

Look for something breaking the connectivity.  The traces are showing failure to open tcp session. There is nothing to be done from cucm at this point of time
