6. Your problem:


Hi,

I have had a look in the forums and wiki, but haven't been able to see a solution (perhaps I have overlooked the obvious).


Anyway, I have two Brekeke Proxy Servers:

Proxy1: IP address 10.10.10.84

Proxy2: 10.10.10.85



I also have two XLite phones:

Phone1: 10.10.10.33 (registered to Proxy 1, with number 1111)

Phone2: 10.10.10.56 (registered to Proxy 2, with number 2222)


This is obviously a test configuration.


I have phone 1 registered with Proxy1, and phone 2 is registered with Proxy2.

Anyway, I am unable to call between phone 1 and phone 2. I can't figure out what dial plan I need on the proxies.


At the moment, I have the following dial plans:


On Proxy1:

Matching Patterns

$request = ^INVITE

To:2(.+)@

Deploy Patterns:

To:%1@10.10.10.85




On Proxy2:

Matching Patterns

$request = ^INVITE

To:1(.+)@

Deploy Patterns:

To:%1@10.10.10.84



It *seems* that the INVITE messages are correctly routed from (for example) XLite phone 1, via Proxy 1 and then Proxy 2, to XLite phone 2222 (i can see this using wireshark). BUT the XLite phones do not ring.


Can anyone help me with this problem - I believe my dialplan is incorrect, but I do not know how to correct it.

Thankyou very much for your help,

Mark
