[OpenSIPS-Users] Changing R-URI depending on the destination

[Toyima Dias]

Hi Bogdan,

Just to let you know why i have to change destiny...

I have gateways RTB, R2, ISDN, QGIS, etc...

If A in PROXY_A wants to call B (B at PROXY_B) on PROXY_B, PROXY_A will have
many routes to reachto usear B, like the following:

directly from PROXY_A to PROXY_B, if it fails for some reason then:
from PROXY_A to ISDN_GW ---> ISDN_B_GW...
.
.
.
In the last case i have to change the R-URI "B at PROXY_B" to
ISDN_NUMBER_ASSIGNED_TO_B at ISDN_GW so it can reach the isdn GW and then
converts this to isdn signaling to communicate with ISDN_B_GW

Does the dialplan module can do this? i mean, assign on-the-flight variables
to change the user-id of the R-URI depending on the destination selected?

Best Regards!
