INCOMING CALLS NOT WORKING

mukthar786 — Tue, 08 Nov 2022 09:10:20 GMT

Two Cisco Server's with CUCM11.5 & ISR 4321( E1 Modules)

for configuring 30 PRI/E1 which Trunk type has to be used SIP TRUNK / H.225

IF I Select SIP TRUNK with Route patterns incoming calls not working for outgoings no problem.

for configuring 30 PRI/E1 which Trunk type has to be used SIP TRUNK / H.225:- its recommended to use SIP trunk as Ciscois removing support of H323 from latest ios versions.

IF I Select SIP TRUNK with Route patterns, that is for outgoing calls and not for incoming.

For incoming you must check the below things.

Dial-peers on the gateway

Voice translation from DID to your extensions.

Inbound CSS on trunk

if you share the voice gateway configurations we might be able to help you quickly.

Hi,

From your first post it sounds like you have a SIP trunk setup in CUCM targetting the Gateway, is that correct?

If so, you have a few configuration additions to make, as shown below. That is also in addition to the advice Nithin provided above.

I saw that you have a voice translation rule configured, but not applied anywhere. Not a big deal if the caller ID delivered from your carrier matches your extension range, but if it doesn't then you need a translation applied somewhere (voice-port, dial-peer or do it in CUCM).

- Create an inbound dial-peer which allows calls to match this on the via header. e.g:

voice-class uri CUCM SIP host ipv4:1.2.3.4 host ipv4:5.6.7.8

- Create a server-group to allow calls from the PSTN to match an outbound dial-peer to CUCM:

voice-class server-group 100 description ***CUCM Cluster*** ipv4: 1.2.3.4 ipv4: 5.6.7.8 preference 1

- Add an incoming dial-peer to match on the via header of the CUCM IP address:

dial-peer voice 100 voip description Incoming to CUBE from CUCM session protocol sipv2 incoming uri via CUCM voice-class codec 1 voice-class sip bind control source-interface GigabitEthernet0/0/0 voice-class sip bind media source-interface GigabitEthernet0/0/0 dtmf-relay rtp-nte no vad

- Add an outbound dial-peer facing CUCM on your gateway:

dial-peer voice 200 voip description Outgoing from CUBE to CUCM session protocol sipv2 session server-group 100 voice-class codec 1 voice-class sip options-keepalive voice-class sip bind control source-interface GigabitEthernet0/0/0 voice-class sip bind media source-interface GigabitEthernet0/0/0 dtmf-relay rtp-nte no vad

Also configure "forward-digits default" under dial-peer 1000. The "forward-digits 0" config is not needed there.
