Hi,
I need help for my SIP implementation. I would like to give you a brief idea of the topology.
We have a single SIP service for the provider which is connecting to the Cisco 2900 router. Internally we have two Microsoft Lync Server which are accepting the voice calls which is working as a PBX.
I have configured DNS SRV on the cisco router and the incoming calls work just perfect. The issue for the outgoing calls which fails.
If I configure IP address instead of the DNS record in the dial peer both incoming and outgoing work perfect, the issue arises when I use DNS instead of IP address
Find attached the configuration and debugs for both working and not working of Cisco Router.
I would appreciate if you can assist me in this.
Regards,
Abbas Mirza
