iPhone Jabber 11.5.2 registered with CUCM 8.6.2 could not make any outbound calls

tacl75 · ‎03-22-2016

Hi,

I have configured my Jabber on iPhone with CUCM 8.6.2 and got it registered successfully. However, I could not make any outbound calls or receive any incoming calls.

The moment I make an outbound internal call, the call setup is completed but Jabber will be unregistered by itself and call disconnected.

The moment I make an inbound internal call to the jabber phone, the jabber phone rings for 2secs and unregistered by itself and call disconnected.

Does anyone has the same experience before ?

Thanks,

Tony

My Jabber is using 11.5.2 and CUCM is 8.6.2.24097-1.

Hi guys,

This is my call flow:

Jabber(VPN) -> Int FW -> TRP / CUCM -> Office IP phones

I have arranged for a Firewall traces and see these pass and drop logs:

Pass Logs:

[fw_4] eth1-01:i[64]: 10.159.197.38 -> 10.92.254.15 (TCP) len=64 id=44168

TCP: 49616 -> 8443 .S.... seq=ec1c1c18 ack=00000000

[fw_6] eth1-01:i[64]: 10.159.197.38 -> 10.92.254.15 (TCP) len=64 id=60258

TCP: 49617 -> 6970 .S.... seq=50fd0fe7 ack=00000000

Drop Logs:

;[cpu_0];[fw_0];fw_log_drop: Packet proto=6 10.171.253.78:58802 -> 10.159.197.38:49587 dropped by fw_handle_first_packet Reason: Rulebase drop - rule 100;

It seems to be that CUCM is sending packets in high port range which I thought CUCM only send in 16384-32767 range ? Does anyone has the similar experience that CUCM is sending higher range port numbers than 32767?

Any advice will be much much appreciated.

Thanks,

Tony
