Good afternoon…
I have the following scenario that seems to be troubling me quite alot.
I have a working IPSEC VPN connection through a CCR1009 and RB4011 two remote sites.
Lets name the sites
CCR1009 SITE A with IP 172.21.1.1 172.21.0.0/16
RB4011 SITE B with IP 172.11.1.1 172.11.0.0/16
SITE B has a VoIP PABX Yeastar S412 with an IP of 172.11.10.99
I have two SIP extentions created on the PABX network.
Extention 9
Extention 10
I am registering these extentions with SIP port 6060 instead of 5060 i.e Ext 9 uses SIP Server 172.11.10.99:6060
The soul purpose is to take a GXP2130 Grandstream device and Register ir remotely on SITE A with extention 9 and a Zoiper Account on SITE A with extention 10.
My problem is as follows
The GXP2130 registers through the IPSEC tunnel but fails to Dial Out.
It receives incoming calls from extentions from site B though without any problem and voice passes through just fine.
The Zoiper extention on the other hand (extention10) has no such issues. It can dial out from SITE A and receive calls from SITE B so it can’t be a port problem.
Bot sites ping each other and its devices just fine.
i.e 172.21.1.1 pings 172.11.1.1 and vice versa
172.21.1.1 pings 172.11.10.99
I failed to mention that the GXP2130 has a static IP of 172.21.10.100 on SITE A which is pingable also from SITE B (172.11.1.1 pings 172.21.10.100)
Any ideas as to what is causing the GXP2130 not being able to dial out?
Thanks in advance.
