[Freeswitch-users] Sequential endpoint bridge question.

[ocset]

Hi

I have a setup where I am using a GXW4104 FXO gateway to access a GSM 
endpoint. With a simple dialplan, making calls works great.

However, I am trying to setup a "Sequential Call Routing" where 
Freeswitch first tries the GSM endpoint and then uses a PSTN line 
instead. With the GSM line, there is always a 5 second delay before the 
call is made, which does not cause an issue with a simple dialplan, but 
when I try the a sequential

Here is an example of the simple dialplan which works

<extension name="Standard Call">
<condition field="destination_number" expression="^(\d{10})$">
<action application="bridge" data="sofia/internal/$1 at 192.168.0.160:5064" />
</condition>
</extension>

<extension name="Standard Call - Seq">
<condition field="destination_number" expression="^(\d{10})$">
<action application="bridge" 
data="{ignore_early_media=true}sofia/internal/$1 at 192.168.0.160:5064 | 
sofia/internal/$1 at 192.168.0.160:5060" />
</condition>
</extension>

What can I do to get Freeswitch to wait longer for the first endpoint or 
is there a better way to achieve this? Should I have two dialplans, one 
after another, that will execute the second if the GSM one fails?

Thanks in advance
