Title: Using SIP Proxy for HA GVP
Post by: letrung on May 25, 2017, 03:59:52 AM

hello eveyone,

i am trying to deploy genesys voice platform using SIP Proxy for HA SIP Server and supporting Resource manager active-active model.
My Lab model as bellow:
- two SIP Proxys active- active  (use sip port 12060 )
- two SIP Server primary- secondary
- two RM Servers  : active- active

[b]With integrating SIP Proxy - SIP Serve[/b]r : i used  "en-SIPS-8.1.1-SIPProxyDeployment-book", it mentioned using DNS based distribution with ( A record , SRV record) to configure DN of type Voice over IP Service, so i did steps as bellow. Has anyone could help me review my steps and configuration parameter is right or not ?

[b]A Record:
[/b]
sip-proxy.ipccbdg.com  172.16.1.12
sip-proxy.ipccbdg.com  172.16.1.13
sip-proxy01.ipccbdg.com  172.16.1.12
sip-proxy02.ipccbdg.com  172.16.1.13


[b]SRV Record:[/b]

_sip._udp.sip-proxy.ipccbdg.com.            300  IN    SRV 0 50 12060 sip-proxy01.ipccbdg.com.
_sip._udp.sip-proxy.ipccbdg.com.            300  IN    SRV 0 50 12060 sip-proxy02.ipccbdg.com.

_sip._tcp.sip-proxy.ipccbdg.com.            300  IN    SRV 0 50 12060 sip-proxy01.ipccbdg.com.
_sip._tcp.sip-proxy.ipccbdg.com.            300  IN    SRV 0 50 12060 sip-proxy02.ipccbdg.com.

[b]And configure DN of Voice over IP service as bellow:[/b]

contact              sip-proxy.ipccbdg.com
external-contact sip-proxy.ipccbdg.com:12060
oos-check          5
oos-force          5
service-type      sip-outbound-proxy

One more, about documents to integare RM with SIP Proxy i can not found on Genesys documentaion,Could  anyone Share it ?


Thank you my friends,

There is no special steps, so just follow the standard guide for MediaServer integration

What kind of problems are you having?  Have you tested the basic install of sip proxy.  I have done the exact deployment you're describing 3 years ago and not much has changed in this department.  Make sure all of your "contact" or "contact-lists" are specified with sip:ip.  Also... I believe the rms have an option for "routefailover", you may need to adjust that parameter.  Lastly, whatever gateway /sbc you're using is going to need to support a path-check of some kind (monitor the proxies using options messages). 

Voip dn config - external contact you're missing a ':'

All of this is coming from memory, if you need more help, start with the basics and post sip log files.

Howerver, on server installed Sip server i can use cmd to resolve FQDN SRV _sip._udp.ipcchcm.com ( and tcp)  and on GA i saw sipserver, sip_proxy applications is start (green).

On that server can you ping reverse (-a) by that IP?
