[OpenSER-Users] Preserving original number when using alias_db_lookup

[Stagg Shelton]

I will re-read the lookup function documentation.

The reason why I am having to do this is because in my particular case  
I have many asterisk PBX's registering to OpenSER.  When asterisk  
registers to OpenSER it has a contact id in the REGISTER message of s at w.x.y.z 
.  After using alias_db_lookup OpenSER is using the contact id in the  
To: field.  When the message gets to asterisk, I cannot route it to  
the correct extension, IVR, Queue because the message is being sent to s at w.x.y.z 
   instead of 5551212 at w.x.y.z

Thanks
Stagg
