We have a customer who uses a SIP trunk for PSTN connectivity with a Cisco Voice Gateway.    IP Phone -----> CUCM ---SIPTrunk--> CUBE ---SIPTrunk---> PSTN Provider   There's a issue where organization cannot make more than 3 concurrent outgoing calls. SIP Trunk has 30 Sessions allowed from Service Provider Side. It was working without an issue for more than one year and suddenly this issue came up. When I looked into gateway SIP traces, I noticed following;   Cube receives Invite from CUCM   *Sep 12 13:05:15.318: //-1/xxxxxxxxxxxx/SIP/Msg/ccsipDisplayMsg: Received: INVITE sip:1090773842920@10.8.43.231:5060 SIP/2.0 Via: SIP/2.0/UDP 10.1.140.1:5060;branch=z9hG4bK5a228115041dbe From: "MALINDA DIAS" <sip:68819@10.1.140.1>;tag=33143171~448cfc3a-4ede-45f4-aca8-9641915fba54-64047908 To: <sip:1090773842920@10.8.43.231> Date: Thu, 12 Sep 2019 12:46:10 GMT Call-ID: 4a76da80-d7a13e12-53a06e-18c010a@10.1.140.1 Supported: timer,resource-priority,replaces Min-SE: 900 User-Agent: Cisco-CUCM10.5 Allow: INVITE, OPTIONS, INFO, BYE, CANCEL, ACK, PRACK, UPDATE, REFER, SUBSCRIBE, NOTIFY CSeq: 101 INVITE Expires: 180 Allow-Events: presence, kpml Supported: X-cisco-srtp-fallback,X-cisco-original-called Call-Info: <sip:10.1.140.1:5060>;method="NOTIFY;Event=telephone-event;Duration=500" Call-Info: <urn:x-cisco-remotecc:callinfo>;x-cisco-video-traffic-class=DESKTOP Cisco-Guid: 1249303168-0000065536-0000241771-0025952522 Session-Expires: 1800 P-Asserted-Identity: "MALINDA DIAS" <sip:68819@10.1.140.1> Remote-Party-ID: "MALINDA DIAS" <sip:68819@10.1.140.1>;party=calling;screen=yes;privacy=off Contact: <sip:68819@10.1.140.1:5060>;+u.sip!devicename.ccm.cisco.com="SEPC4B9CD819ADD" Max-Forwards: 69 Content-Type: application/sdp Content-Length: 350 v=0 o=CiscoSystemsCCM-SIP 33143171 1 IN IP4 10.1.140.1 s=SIP Call c=IN IP4 10.8.26.20 b=TIAS:64000 b=AS:64 t=0 0 m=audio 29338 RTP/AVP 0 8 116 18 101 b=TIAS:64000 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:116 iLBC/8000 a=maxptime:20 a=fmtp:116 mode=20 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15   Cube Sends invite towards PSTN Provider with out RTP port mentioned    *Sep 12 13:05:15.338: //1190571/4A76DA800003/SIP/Msg/ccsipDisplayMsg: Sent: INVITE sip:0773842920@172.16.2.1:5060 SIP/2.0 Via: SIP/2.0/UDP 10.8.43.231:5060;branch=z9hG4bK4237622AB From: "MALINDA DIAS" <sip:112990000@172.16.1.1>;tag=D1239FF8-87A To: <sip:0773842920@172.16.2.1> Date: Thu, 12 Sep 2019 13:05:15 GMT Call-ID: CBF134D6-D49411E9-B85A81D1-69F88A34@10.8.43.231 Supported: 100rel,timer,resource-priority,replaces,sdp-anat Min-SE: 1800 Cisco-Guid: 1249303168-0000065536-0000241771-0025952522 User-Agent: Cisco-SIPGateway/IOS-12.x Allow: INVITE, OPTIONS, BYE, CANCEL, ACK, PRACK, UPDATE, REFER, SUBSCRIBE, NOTIFY, INFO, REGISTER CSeq: 101 INVITE Timestamp: 1568293515 Contact: <sip:112990000@10.8.43.231:5060> Expires: 180 Allow-Events: telephone-event Max-Forwards: 68 Session-Expires: 1800 Content-Type: application/sdp Content-Disposition: session;handling=required Content-Length: 346 v=0 o=CiscoSystemsSIP-GW-UserAgent 394 794 IN IP4 10.8.43.231 s=SIP Call c=IN IP4 10.8.43.231 t=0 0 m=audio 0 RTP/AVP 0 8 18 100 101 c=IN IP4 10.8.43.231 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:100 X-NSE/8000 a=fmtp:100 192-194 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16   PSTN Provider rejects call    *Sep 12 13:05:15.362: //1190571/4A76DA800003/SIP/Msg/ccsipDisplayMsg: Received: SIP/2.0 480 Temporarily Unavailable Via: SIP/2.0/UDP 10.8.43.231:5060;branch=z9hG4bK4237622AB Call-ID: CBF134D6-D49411E9-B85A81D1-69F88A34@10.8.43.231 From: "MALINDA DIAS"<sip:112990000@172.16.1.1>;tag=D1239FF8-87A To: <sip:0773842920@172.16.2.1>;tag=16010209-ZAJ01ae209672a CSeq: 101 INVITE User-Agent: ZTE Softswitch/1.0.0 Reason: Q.850;cause=34;text="Resource unavailable" Content-Length: 0   PSTN Provider states they don't receive a RTP port in initial invite so they reject it from their side.

We have a customer who was running uccx 9.x and recently upgraded into uccx 11.5 with Finess. They use 7942 phones with 2 lines, 1st line Non-ACD (Personal Ext) and 2nd line IPCC extension. In the UCCX 9.0 / CAD environment Agents used to receive calls via IPCC extension as well as call from a hunt that configured with group of agent's Non-ACD lines. This worked without an issue.   However in UCCX 11.5, when Agent receives a call to Non-ACD line, Finess goes not ready state. Imagine agent is on a IPCC call and later received a hunt call to his personal line, and hangs up the IPCC call first, but his state remain Not Ready. Until Non-ACD hunt call is hangup he cannot ready his Finess state.   I came through that from UCCX 9.x onward UCCX supports multilines and UCCX will consider phone's state rather than only IPCC extension. Is this is the issue ? How to make UCCX do not monitor agent's personal line ?   UCCX 11.5 / CUCM 11.5 ... View more

We installed 2 WS-C3850-12S switches and 2 WS-C3850-24T  switches recently.  Stacked 4 of them and stack works fine. However when SFP modules (GLC-SX-MMD=) connected into 12s switches, ports get error disabled randomly. Some of the ports working fine, but others remain in shut state. We changed SFP modules, tried "errdisable detect cause gbic -invalid " command but still no change.  Anyone had same issue or know the reason for this ? I'm sure SFP modules are genuine.  Thank you very much. ... View more

Hi, One of our clients has a PoE+ Cisco 24 port switch and 24 Cisco IP phones attached into it. Switch is getting power via a UPS. When ever there's a power failure, UPS can provide power until generator kicks in.  The issue is rather strange. When ever main power goes down and UPS kicks in, a Cisco DX650 phone reboots itself, while the rest of the phones attached to switch (3905, 7942) remain to work without any issue. I thought may be power drawn out from the switch is high and it causes this but when i check power inline states ;  Module Available Used Remaining (Watts) (Watts) (Watts) ------ --------- -------- --------- 1 370.0 85.8 284.2 Which indicates switch is quite comfortable supplying the required power. This is the DX650's power stats; Interface Admin Oper Power Device Class Max (Watts) --------- ------ ---------- ------- ------------------- ----- ---- Gi1/0/1 auto on 13.7 IP Phone DX650 4 30.0 What could be the reason for this ? Thanks in advance.  ... View more
