CP 3905 configure for SRST

[tanim1601]

Hi all,

I am using CP 3905 now I tried to configure SRST (10.5) but it cant register with the router. Is there any compatibility requirement for it? Can any one answer my question?

Thanks,

Tanim

you can check compatiblity matrix for SRST 10.5 along with endpoints. You need take debug to check why phones is not registering ? arey you getting registered message from the phone on GW ??

Hi all, I did not debug with ccsip mess.I will try it tomorrow. Its first time I am trying to configure SRST. Here is the configuration of SRST:

!
ip dhcp pool VOICE_PCL
 network 10.14.30.0 255.255.255.0
 dns-server 192.168.12.5 192.162.12.16

As 3905 is sip should I need to source-address port to 5060 ? Please advice me..

Thanks

Ur config for sccp srst. It won't work for sip.

Go through srst config guide

[Jaime Valencia]

It seems to be supported, have you already configured SIP SRST??

[Mohammed al Baqari]

Can you share the output of debug ccsip mess when the phone is trying to register? Also, can you share your SRST config.

[HARIS_HUSSAIN]

CP 3905 is a SIP Only Phone you can refer the data sheet.

http://www.cisco.com/c/en/us/products/collateral/collaboration-endpoints/unified-sip-phone-3905/data_sheet_c78-651588.html.

1.  Make sure you add Routers IP as SRST Reference in CUCM

• Go to Systems>SRST
• Add New SRST Refernce
• Configure The SIP Network/IP address as Routers IP.( You can keeo 5060 port)
• Save
• Apply the same to the Device pool of the required. phones. and reset the phones. 
• Verify that Phone has downloaded the SRST Reference. You do same via Settings and Browse to the Unified CM List. SRST Ip will be displayed as last one after CUCM IP address

2. Now configure the router with SIP Srst commands. Below is an example

voice service voip
ip address trusted list

ipv4 0.0.0.0 0.0.0.0

< You can allow only your subnets>
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip

sip
registrar server expires max 600 min 60

sip-ua
registrar ipv4:172.16.31.240 expires 600
<IP of SRST Gateway>

voice class codec 1
codec preference 1 g711ulaw
codec preference 2 g711alaw
codec preference 3 g729r8

voice register global
mode srst OR  mode esrst
system message Fallback Mode
timeouts interdigit 7
max-dn 5
max-pool 2

voice register pool 1
id network 172.16.31.0 mask 255.255.255.0
<NEED TO ADJUST THIS IP and MAs as per your network>
voice-class codec 1
dtmf-relay rtp-nte

Finally test the same.

Please rate if found useful.

Thanks

Hi Haris,

Thank you for your post. Today I've tried with your configuration but no luck yet. My phone 3905 frequently goes for registering and provisioning state but cant not register with SRST. :(

Here is the error message at SRST:

Any suggestion????

[Mohammed al Baqari]

Try the following commands:

voice service voip

sip

bind all source vlan 30

!

voice register global

source-add 10.14.30.1

[HARIS_HUSSAIN]

Is the phone registered  to CUCM and in the Phone can you see the SRST Ip.

Go to Settings>Device Configuration. You should see the SRST IP address there.

• When you try to test the SRST Scenario, you should disable the connective to All the CUCM Nodes. In cucm Phone will show as unregistered.
• Try to capture debug ccsip logs and attach the same.
• Also add the SIP Bind source Command
• voice service voip 

sip
bind all source-interface gig0/0

• I believe your phone is not sending any requests to the Router.
